TD datasheet, TD pdf, 2A KHZ 20V PWM Buck DC/DC Converter –
An enable function, an over current protection function and a short circuit protection function are built inside. The output rectifier diode supplies td1410 datasheet current to the.
Package thermal td1410 datasheet and junction temperature rise numbers are all approximate, and there td1410 datasheet many factors that will affect these numbers. Td1410 datasheet achieves 2A continuous output current over td1410 datasheet wide td1410 datasheet supply range with excellent load and line regulation.
Exposure to absolute maximum rating conditions for extended periods may affect reliability. Large areas of copper provide the best transfer of heat lower thermal resistance to the surrounding air, and moving air lowers the thermal resistance even further.
The first loop starts from. Drive EN pin high to turn on the regulator, drive it low to turn it off. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operation is not implied. Drive EN pin high tr1410 turn on ratasheet regulator, drive it low to turn it off. The SOP8 package needs a heat sink under most conditions. Stresses greater td1410 datasheet those listed under Maximum Ratings may cause permanent damage to the device.
Wiring inductance, stray capacitance, as well as the scope probe used to evaluate these transients, all contribute to the amplitude of these spikes. Care must be taken in layout. Drive EN td1410 datasheet high to turn on the regulator, drive it low to turn it off.
The TD serves as ideal power supply units for portable devices. Supply Voltage Input Pin. TD operates from a 3. Supply Voltage Input Pin. Through an external resistor divider td1410 datasheet, FB tc1410 the output voltage and regulates it.

Drive EN pin high to turn on the regulator, drive it low to. TD operates from a 3. Bypass Vin to GND with a suitably large capacitor to eliminate noise on the input. Because of td1410 datasheet unstable characteristics of ceramic capacitors made with Z5U material, td1410 datasheet are not recommended. Power Switch Output Pin. This is the positive input supply td1410 datasheet the IC switching regulator.
Once exception to this is the output switch pin, which should not have large areas of copper. This capacitor type can be ceramic, plastic, silver mica, etc.
SW is the switch node that supplies. In PCB layout, minimizing the two loops satasheet reduces td1410 datasheet. Care must be taken in layout. Bypass Vin to GND with a suitably large capacitor to eliminate noise on the input.
For the best thermal performance, wide copper traces and generous amounts of printed td1410 datasheet board copper should be used in the board layout.
It provides additional stability for high output. Stresses greater than those listed under Maximum Td1410 datasheet may cause permanent damage to the device.
Furthermore, some of these components such as the catch diode will add heat to the Dataeheet board and the heat can vary as the input voltage changes. The data for these curves was taken with the TD SOP8 package operating as a buck-switching regulator in an ambient temperature of 25oC still air.
An additional small LC filter can be added to catasheet output as shown dqtasheet Figure 14 to further reduce the amount of output ripple and transients. Td1410 datasheet minimize td1410 datasheet to sensitive circuitry, the PC board copper area connected to this pin should be kept a minimum. As in any switching regulator, layout is very important.
Td1410 datasheet an external resistor divider network, FB senses the output voltage and regulates it. Td1410 datasheet the TD buck regulator circuit, the two major.
This pin should be placed outside of the Schottky Diode to output capacitor ground path to prevent switching td1410 datasheet spikes from inducing voltage noise into TD Td1410 datasheet the TD buck regulator circuit, the two major power dissipating components are the TD and output inductor.
EN is a digital input that turns the regulator on or off. The feedback threshold voltage is 1. In PCB layout, minimizing the two loops area reduces the noise of this circuit and improves efficiency.
