Technology
FP3843
OFF-LINE CURRENT MODE PWM CONTROL IC
GENERAL DESCRIPTION
The FP3843, a 1-chip composed of high-current totem pole output circuits with a PWM latch, current sense comparator and an error amplifier, the FP3843 contains a 5V precision voltage reference regulator, under-voltage lockout circuit (UVLO), oscillator circuit, applied to offer space and low cost in many applications such as the DC/DC converter and off-line switching power supply. Using few external components, FP3843, a high performance integrated IC, is designed for a control circuit. The circuit diagram of the typical application example is as below.
FEATURES
Precision Reference Voltage: 5.0V (±1%) Low start-up current: typ.
