Tps61022rwur vqfn-7 DC-DC power chip shipped at a low price
describe
Tps61022 provides power solutions for portable devices and Internet of things devices powered by various batteries and * level capacitors. The tps61022 has a small valley switching current limit of 6.5 a over the entire temperature range. Tps61022 has a wide input voltage range of 0.5 V to 5.5 V and supports the application of standby power supply for class * capacitors, which may deeply discharge class * capacitors.
When the input voltage * * 1.5 V, the tps61022 operates at a switching frequency of 1 MHz. When the input voltage * * 1.5 V drops to 1 V, the switching frequency gradually decreases to 0.6 MHz. Amode pin sets tps61022 to operate in power saving mode or forced PWM mode under light load conditions. Tps61022 only consumes 26 µ weak current under voutin light load. During shutdown, the load is disconnected from the input power supply. Tps61022 has 5.7-vout overvoltage protection, output short circuit protection and thermal shutdown protection
Tps61022 adopts 2-mm × The 2-mm vqfn package and a small number of external components provide a very small solution size.
