The Texas Instruments UCC2570N is a voltage mode Pulse Width Modulator (PWM) controller suitable for isolated switching power supplies. It is designed for applications such as off-line power supplies and DC/DC converters in distributed power systems or telecom power sources.
Key electrical specifications include a 15V VCC, a 1A driver output current, and a maximum switching frequency of 700kHz. The device features adjustable switching frequency, current limiting, multi-topology support, programmable maximum duty cycle, soft start, and a synchronization pin. It also includes integrated oscillator/voltage feed forward compensation, an accurate duty cycle limit, and an accurate volt-second clamp.
Operational characteristics include a wide input voltage range for feed forward compensation (5:1) and response to input voltage changes (4:1). The controller offers fault protection with fault counting and shutdown capabilities, which can be latch off or automatic. It also supports soft stop and is optimized for synchronous rectification.
The UCC2570N is available in SOIC (D), TSSOP (PW), and PDIP (N) packages, all supporting surface mount or through-hole mounting depending on the package type. The operating temperature range is -40°C to 85°C.
