UC2875-EP Datasheet (Texas Instruments) - Phase Shift Resonant Controller

UC2875-EP, Phase Shift Resonant Controller

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 per

UC2875-EP 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 fa
