Technology
FP5001
PWM CONTROL IC
WITH SCP/DTC FUNCTION
GENERAL DESCRIPTION
The FP5001, a 1-chi p co mposed of o pen collector tran sistor o utput pulse-wi dth-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.
FEATURES
Reference Voltage Precision: 2%
Output sink current up to 100mA
Low quiescent supply current
Wide operating voltage range: 3.6~40V
Variable dead-time control (DTC)
UVLO protection function
SCP protection function
Oscillator Frequency: Max. 500KHz
Package: PDIP8/ SOP8
