Switchmode Pulse Width Modulation Control Circuit

The PJ494 incorporates on a single monolithic chip all the functions required in the construction of a pulse width-modulation control circuit. Designed primarily for power supply control, these devices offer the systems engineer the flexibility to tailor the power supply control circuitry to his application.

FEATURES

•  Complete PWM Power Control Circuitry

•  Uncommitted Outputs for 200mA Sink or Source Current

•  Output Control Selects Single-Ended or Push –Pull Operation

•  Internal Circuitry Prohibits Double Pulse at Either Output

•  Variable Dead-Time Provides Control over Total Range

•  Internal Regulator Provides a Stable 5-V Reference Supply, 5%
