Product Introduction

The UCC3808A is a family of BiCMOS push-pull, high-speed, low-power, pulse-width modulators. Contains all control and drive circuitry required for UCC3808A offline or switching with minimal number of external components, power supply, DC to DC fixed frequency current mode.

The UCC3808A dual-output drive stage is arranged in a push-pull configuration. Half of the oscillators of the two output switches use one switch flip-flop frequency. The dead time between two outputs, typically between 60 nanoseconds and 200 nanoseconds, depends on the values of capacitance and resistance, limiting the duty cycle of less than 50% per output stage.

The UCC3808A series offers a choice of packages, temperature range options, and undervoltage lockout levels.
