Frequently Asked Questions
What is the maximum switching frequency of the UCC38502NG4?
The UCC38502NG4 supports switching frequencies up to 115 kHz. This relatively high frequency allows designers to use smaller magnetic components such as inductors and transformers, which is beneficial for reducing the overall size and cost of AC/DC power supply designs.
What control modes does the UCC38502NG4 support?
The UCC38502NG4 can be programmed for current mode, voltage mode, and power factor control (PFC) operation. This flexibility makes it suitable for a wide range of converter topologies, including boost PFC pre-regulators and downstream PWM converters in two-stage offline power supplies.
What input voltage range does the UCC38502NG4 require?
The UCC38502NG4 requires an input supply voltage between 10.3 V (minimum) and 15 V (maximum), with a nominal operating voltage of 12 V. A startup bootstrap circuit or auxiliary winding is typically used to supply this voltage during initial power-up in offline converter designs.
What package does the UCC38502NG4 use, and is it suitable for prototyping?
The UCC38502NG4 is available in a 20-pin plastic dual-in-line (PDIP) through-hole package, designated R-PDIP-T20. The PDIP format is well suited for prototyping on breadboards and perfboards, and fits standard 0.3-inch DIP sockets commonly used in power electronics development and lab evaluation boards.
