NJM3524
SWITCHING REGULATOR CONTROL CIRCUIT
■ GENERAL DESCRIPTION
■ PACKAGE OUTLINE
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.
