This device is a monolithic high voltage power switching regulator which combines a VDMOS Sense FET with a voltage mode PWM control block. The integrated PWM controller features include a fixed oscillator, Under Voltage Lock Out UVLO protection, Leading Edge Blanking LEB , optimized gate turn-on/ turn-off driver, thermal shut down protection TSD , temperature compensated precision current sources for loop compensation and fault protection circuitry. When compared to a discrete MOSFET and controller or RCC switching converter solution, the FSDM101 reduces total component count, design size, weight and at the same time increases efficiency, productivity, and system reliability.
