FP3842
OFF-LINE CURRENT MODE PWM CONTROL IC
GENERAL DESCRIPTION
The FP3842, a 1-chip composed of high-current totem pole output circuits with a PWM latch, current sense comparator and an error amplifier, the FP3842 contains a 5V precision voltage reference
regulator, under-voltage lockout circuit (UVLO), oscillator circuit and a green power function, applied to offer space and low cost in many applications such as the DC/DC converter and off-line green mode adaptor or switching power supply.
