Product details

Description

The UTC UC2842A/2843A are high performance fixed frequency current mode controllers that specifically designed for Off-Line and DC to DC converter applications with minimal external parts count.

The differences between UC2842A and UC2843A are the under-voltage lockout thresholds.

Features

S.
Operation output switching frequency up to 500 kHz.
Automatic feed forward compensation.
Latching PWM for cycle-by-cycle current limiting.
High current totem pole output.
Internally trimmed reference with under voltage lockout.
UVLO with hysteresis.
Low startup and operating current.
