UCC28700DBVR Description

Short technical summary and product information.

The Texas Instruments UCC28700DBVR is an AC/DC switching regulator designed for constant-voltage, constant-current (CV/CC) output regulation with primary-side regulation (PSR). This PSR capability eliminates the need for an opto-coupler, simplifying the design and reducing component count.

 

The device operates with a Flyback topology and features quasi-resonant valley-switching for high overall efficiency. It supports a wide input voltage range of 9V to 35V and offers a maximum switching frequency of 130 kHz, enabling high-power density charger designs. Key features include current limiting, overvoltage protection, and a low no-load power consumption of less than 30 mW, contributing to 5-star energy ratings.

 

The UCC28700DBVR is housed in a SOT-23-6 package, suitable for surface mounting. Its operating temperature range is -20°C to 125°C (TJ). The controller provides ±5% voltage and current regulation and includes programmable cable compensation for precise output control.

 

This component is ideal for various offline power supply applications, including adapters, chargers, and auxiliary power supplies where efficiency, compact size, and reliable regulation are critical.
