Switching Regulator Control Circuit

Manufacturer's part number :

NJM3524D

Manufacturer New Japan Radio

New Japan Radio

Description :

The NJM3524 of regulating pulse width modulators contains all of the control circuitry necessary to implement switching regulators of either polarity converters and voltage doublers, as well as other power control applications. This device includes a 5V voltage regulator capable of supplying up to 50mA to external circuitry a control amplifier, an oscillator, a pulse width modulator, a phase splitting flip-flop, dual alternating output switch transistors, and current limiting and shut-down circuitry. Both the regulator output transistor and each output switch are internally current limited and, to limit junction temperature, an internal thermal shut-down circuit is employed.
