UC2875N Description

Short technical summary and product information.

The UC2875N from Texas Instruments is an integrated circuit designed for controlling a bridge power stage through phase-shifting. This allows for constant frequency pulse-width modulation combined with resonant, zero-voltage switching, enabling high efficiency performance at high frequencies.

 

This controller supports voltage or current mode operation and includes features such as adjustable switching frequency, an error amplifier, soft start, soft switching, and synchronization. It has a maximum duty cycle of 100% and offers programmable output turn-on delay. The device operates with a supply voltage range of 9.5V to 20V and features undervoltage lockout (UVLO) at 10.75V/9.25V.

 

Key electrical characteristics include four 2A totem pole outputs and a 10MHz error amplifier. It also incorporates a latched over-current comparator with full cycle restart for fault protection. The operating temperature range is -25°C to 85°C.

 

The UC2875N is available in a 20-PDIP through-hole package. Its design is suitable for applications requiring efficient power conversion at high switching frequencies.
