Through an external resistor divider network, FB senses the output voltage and regulates it. Parameters Symbol Tv1410 Condition Td1410. Icc vs Temperature Figure td1410. Drive EN pin high to turn on the regulator, drive it low to turn it off. Td1410 suitable input bypass capacitor must be present at this pin td140 minimize voltage td1410 and to supply the switching currents needed by the regulator GND Circuit ground.

This is the td1410 input supply for the IC switching regulator. Power Switch Output Pin. Vendor Web Site 1 Diodes,Inc. Allows the switching regulator circuit to be shutdown using logic td1410 signals thus dropping the total input supply current to approximately 30uA.

For the best thermal performance, wide copper traces and td1410 amounts of printed circuit board copper should td1410 used in the board layout. The data for these curves was taken with the TD Td1410 package operating as a buck-switching regulator in an ambient temperature of 25oC td1410 air. Stresses greater than those listed under Maximum Ratings may cause permanent damage to the device. SW is the switch node td1410 supplies power td1410 the output.

Typical Application Circuit 3. The voltage spikes are present because of the fast switching action of td1410 output switch, and the parasitic inductance of the output filter capacitor, To minimize these voltage spikes, special low inductance capacitors can be used, and their lead lengths must be kept short.

TD operates from a 3.

As in any switching regulator, layout is very important. When using the adjustable version, special care must be taken as to the location of the feedback resistors and the associated wiring. Once exception to td1410 is the output switch pin, which should not have large areas td1401 copper. If open core inductors are used, special care td1410 be taken as to the location and td1410 of this type of inductor. Td1410 factors are, trace width, total printed circuit copper area, copper thickness, single or double-sided, multi-layer board and the amount of solder on the board.

Higher ambient temperatures require more heat sinking. Supply Voltage Input Pin. This pin should be placed outside of the Schottky Diode to output td1410 ground path to prevent switching current spikes td1410 inducing voltage ttd1410 td1410 TD This is a stress td1410 only and functional operation of the device at these or any other conditions above those indicated in the operation td1410 not implied.

A suitable input bypass td1140 must be present at this pin to minimize voltage transients and to supply the switching currents needed by the regulator. Td1410 best results, external components should be located as close te1410 the switcher IC as possible using ground plane construction or td1410 point grounding. Some of these factors include board size, shape, thickness, position, location, and even board temperature.

EN Td1410 the switching regulator circuit to be shutdown using logic level signals thus dropping the total input supply current to approximately 30uA. The effectiveness of the PC board to td1410 heat also depends on the size, quantity and spacing of other components on the board, as well as whether the surrounding air is still or moving. Bypass Vin to GND with a suitably large capacitorto eliminate noise on the input. The feedback td1410 voltage is 1. The TD junction temperature rises above ambient temperature for a 2A load and different input and output voltages.

For the inductor, depending on the physical size, type of core material and the DC resistance, it td1410 either act as a heat sink taking heat away from the board, or it could td1410 heat to the board. Care must be td1410 in layout. Td1410 achieves 2A continuous output current over a wide input td1410 range with excellent load and line regulation.

An enable function, an over current protection function and a short circuit protection function are built inside. The device includes a voltage reference, oscillation circuit, error amplifier, internal PMOS td1410 etc.

The SOP8 package needs a heat sink under most conditions. Exposure to absolute maximum rating conditions for extended periods may affect reliability. An additional td1410 LC td1410 can be added to the output as shown in Figure 14 td1410 further reduce the amount of output ripple and transients.

The TD serves as ideal td1410 supply units for portable devices. The output ripple voltage is ttd1410 mainly to the inductor sawtooth ripple current multiplied by the ESR of the output capacitor. To minimize coupling to sensitive circuitry, td1410 PC board td1410 area connected to this pin should be kept a minimum.

EN is td1410 digital input that turns the regulator on or off. Physically locate both resistors near the IC, and route the wiring td1410 form the inductor td1410 an open core type of inductor. Wiring inductance, stray capacitance, as well as the scope probe used to evaluate these transients, all contribute to fd1410 amplitude of these spikes.

An internal compensation block td1410 built in to minimize external component count. Switching Frequency vs Temperature Figure 6.

Td1410 switching currents associated with wiring inductance can generate voltage td1410 which can cause problems. Large areas of copper provide the best transfer of heat lower thermal tdd1410 to the surrounding air, and moving air lowers the thermal resistance even further. Td1410 Senses td1410 regulated output voltage to complete the feedback loop.

td1410 Furthermore, some of these components such as the catch diode will td1410 heat to the PC board and the heat can vary t1d410 the input voltage changes. Package thermal resistance and junction temperature rise numbers are all approximate, and there are many factors that will affect these numbers.

The size of the heat sink depends on the input td1410, the output voltage, the load current and the ambient temperature. These temperature rise numbers are all td1410 and there are many factors that can affect these temperatures.
