Product details

Description

ordering information The UC2875 integrated circuit implements control of a bridge power stage by phase-shifting the switching of one half-bridge with respect to the other, allowing constant frequency pulse-width modulation in combination with resonant, zero-voltage switching for high efficiency performance at high frequencies.This circuit may be configured to provide control in either voltage or current mode operation, with a separate over-current shutdown for fast fault protection.A programm

Features

include an undervoltage lockout which maintains all outputs in an active-low state until the supply reaches a 10.75 V threshold. 1.5 V hysteresis is built in for reliable, boot-strapped chip supply. Over-current protection is provided, and will latch the outputs in the OFF state within 70 ns of a fault. The current-fault circuitry implements full-cycle restart operation. Additional features include an error amplifier with band-width in excess of 7 MHz, a 5 V reference, provisions for soft-starti.
