Product overview
The PWM5034 is a fixed-frequency pulse-width-modulator controller that supports voltage-mode or current-mode power conversion. It provides dual totem-pole output drivers, an error amplifier and an auxiliary operational amplifier for converter control and signal conditioning. Separate sleep, enable and soft-control inputs support power-down and output control. Undervoltage lockout with hysteresis and a power-good indication help coordinate startup. The device can be configured for several converter topologies and selectable maximum duty cycle. The datasheet provides timing, output-drive and application details for selecting the oscillator and integrating the external power stage.
