The UCC28720D from Texas Instruments is an offline AC/DC switching regulator designed for flyback power supplies. It provides isolated-output constant-voltage (CV) and constant-current (CC) regulation without the need for an opto-coupler, utilizing primary-side regulation (PSR) for precise control.
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 80 kHz, enabling high-power density charger designs. It incorporates quasi-resonant valley-switching operation for high efficiency and offers overvoltage, low-line, and overcurrent protection functions, along with programmable cable compensation.
The UCC28720D is housed in a 7-SOIC package and operates within an ambient temperature range of -40°C to 125°C. Its design supports ultra-low standby power without compromising start-up time or output transient response, making it suitable for various power supply applications.
