Texas Instruments UC3526AN, Dual PWM Voltage Mode Controller, 100 mA, 650 kHz 18-Pin, PDIP
Product Details
Product Details
Flyback Controller, Voltage Control, Texas Instruments
The isolated-flyback power supply controller provides Constant-Voltage (CV) and Constant-Current (CC) output regulation to improve transient response to large load steps. Primary-Side Regulation (PSR) eliminates the need for an Optocoupler.
