Description

The FSDM0465RE, FSDM0565RE and FSDM07652RE

are an integrated Pulse Width Modulator (PWM) and

SenseFET specifically designed for high-performance

offline Switch Mode Power Supplies (SMPS) with

minimal external components. This device is an

integrated high-voltage power-switching regulator that

combines an avalanche-rugged SenseFET with a

current mode PWM control block. The PWM controller

includes an integrated fixed-frequency oscillator, under-

voltage lockout, leading-edge blanking (LEB), optimized

gate driver, internal soft-start, temperature-compensated

precise-current sources for a loop compensation, and

self-protection circuitry. Compared with a discrete

MOSFET and PWM controller solution, it can reduce total

cost; component count, size, and weight; while

simultaneously increasing efficiency, productivity, and

system reliability. This device is a basic platform well

suited for cost-effective designs of flyback converters.

1. Start-up: In previous generations of Power Switches the VCC pin had an external startup resistor to the DC input voltage line. In this generation, the start-up resistor is replaced by an internal high-voltage current source. At start-up, the internal high-voltage current source supplies the internal bias and charges the external capacitor (Cvcc) connected to the VCC pin, as illustrated in Figure 17.
