UC2842B/3B/4B/5B UC3842B/3B/4B/5B – HIGH PERFORMANCE CURRENT MODE PWM CONTROLLER

uc2842b3b4b5b-uc3842b3b4b5b---high-performance-current-mode-pwm-controller.pdf

This datasheet describes a family of high-performance current mode PWM controllers designed for off-line and DC-to-DC fixed frequency current mode control schemes.

Key Features:

Trimmed oscillator for precise frequency control up to 500kHz
Current mode operation with automatic feed-forward compensation and latching PWM for cycle-by-cycle current limiting
Internally trimmed reference with undervoltage lockout and high current totem pole output stage
Low start-up and operating current

Family Members:

UC3842B and UC3844B: suited for off-line applications with UVLO thresholds of 16V (on) and 10V (off)
UC3843B and UC3845B: suited for off-line applications with UVLO thresholds of 8.5V (on) and 7.9V (off)
