SMP402, 20-72 VDC Input Non-isolated DC Output

SMP402 1-Watt Buck Regulator IC 20-72 VDC Input Non-isolated DC Output Product Highlights Integrated Power Switch and CMOS Controller * Output

Features

* include high voltage, low RDS(ON), and low capacitance.
Lower capacitance results in a reduction in gate drive power, and also facilitates higher frequency operation.
The controller section of the SMP402 contains all the blocks required to drive and control the power stage: start-up preregulator cir

Applications

* Low capacitance allows for high frequency operation High-voltage Buck Regulator
* Internal pre-regulator self-powers the IC on start-up
* Designed for low power consumption
* Minimum external parts required Built-In Self-protection Circuits
* Undervoltage lo
