UCC28711DR Description

Short technical summary and product information.

The Texas Instruments UCC28711DR is an AC/DC switching regulator designed for offline power supply applications. It provides constant-voltage and constant-current output regulation without the need for an optical coupler, utilizing primary-side regulation (PSR).

 

Key features include a < 10-mW no-load power consumption, ±5% voltage and current regulation across line and load, and a 700-V start-up switch. The device operates with a maximum switching frequency of 100 kHz, enabling high-power density charger designs. It incorporates resonant valley-switching operation for high efficiency and frequency jitter to ease EMI compliance.

 

The UCC28711DR includes overvoltage, low-line, and overcurrent protection functions. It also features an NTC resistor interface for cable compensation. The device is housed in a 7-SOIC surface-mount package and operates within a temperature range of -40°C to 125°C.

 

This controller is suitable for various power supply designs requiring isolated outputs and efficient regulation.
