IL494[PWM Control Circuit]

other part :IL494D   IL494DT   IL494N  

The IL494 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, the IL494 contains an on-chip 5-volt regulator, two error amplifiers, adjustable oscillator, dead-time control comparator, pulse-steering flip-flop, and output-control circuitry. The uncommitted output transistors provide either common-emitter or emitter-follower output capability. Push-pull or single-ended output operation may be selected through the output-control function. The architecture of the IL494 prohibits the possibility of either output being pulsed twice during push-pull operation.

FEATURE
• Complete PWM Power Control Circuitry
• Uncommitted Outputs for 200 mA Sink or Source
• Output Control Selects Single-Ended or Push-Pull Operation
• Internal Circuitry Prohibits Double Pulse at Either Output
• Internal Regulator Provides a Stable 5 V Reference Supply
• Variable Dead-Time Provides Control Over Total Range

TL496C[9-V POWER-SUPPLY CONTROLLERS]

other part :TL496CD   TL496CP   TL496Y  

description
The TL496C power-supply control circuit is designed to provide a 9-V regulated supply from a variety of input sources. Operable from a 1- or 2-cell battery input, the TL496C performs as a switching regulator with the addition of a single inductor and filter capacitor. When ac coupled with a step-down transformer, the TL496C operates as a series regulator to maintain the regulated output voltage and, with the addition of a single catch diode, time shares to recharge the input batteries.
