The Texas Instruments UCC28086DR is a BiCMOS pulse width modulation (PWM) controller family for dc-to-dc or off-line fixed-frequency current-mode switching power supplies. The dual output stages are configured for the push-pull topology, with outputs switching at half the oscillator frequency. This controller offers programmable slope compensation, cycle-by-cycle current limiting, and a low start-up current of 120 µA. It features a single external component oscillator programmable from 50 kHz to 1 MHz and a high-current totem-pole dual output stage capable of driving push-pull configurations.
Key electrical features include a voltage range of 4.1V to 15V, a maximum duty cycle of 49%, and a frequency of 200kHz. The device includes a current sense discharge transistor to improve dynamic response and an internally trimmed bandgap reference. It also incorporates undervoltage lockout with hysteresis.
The UCC28086DR is suitable for applications such as high-efficiency switch-mode power supplies, telecom dc-to-dc converters, point-of-load or point-of-use power modules, and low-cost push-pull and half-bridge applications. It is available in an 8-SOIC package and is designed for surface mount.
This controller provides essential features for efficient power conversion in various electronic systems.
