BIPOLAR ANALOG INTEGRATED CIRCUIT

PC494

SWITCHING REGULATOR CONTROL CIRCUIT

<R>

DESCRIPTION

The

PC494 is a PWM type switching regulator control circuit.

Included in this device are a 5 V voltage reference, dual error amplifiers, a variable frequency sawtooth-wave

generating oscillator, a comparator for dead-time control, a flip flop, dual alternating output switches, and a buffer to

output source and sink currents.

Error amplifiers have wide common mode input voltage capability, and circuits for voltage feedback and over current

protection are easy to configure. The

PC494 can be applied to all types of switching regulators, including chopper

type regulators.

•

Internal 5 V output voltage reference circuit

•

Error amplifiers with phase-compensating function

•

Providing master-slave operation (synchronizing multiple ICs)

•

With malfunction prevention circuit for low level supply voltage

•

Package variations available for different applications
