FP5001-PWM CONTROL IC WITH SCP/DTC FUNCTION


FP5001 PWM CONTROL IC WITH SCP/DTC FUNCTION
General Description
Download
 The FP5001, a 1-chip composed of open collector transistor output pulse-width-modulation control circuits with an error amplifier and dead-time comparators (DTC), the FP5001 contains a 1.0V precision voltage reference regulator, under-voltage lockout circuit (UVLO), short circuit protection circuit (SCP), applied to offer space and low cost in many applications such as the DC/DC converter and backlight inverter.
 Using few external components, FP5001, a high performance integrated IC, is designed for a control circuit. The circuit diagram of the typical application example is as below.
