NJM2362

CURRENT MODE FLYBACK PWM SWITCHING REGULATOR

■ GENERAL DESCRIPTION

NJM2362 is the current mode flyback type, switching supply

voltage IC.

Totempole type output, which can drive MOSFET in high speed

operation directly.

As to the functional protection, internalizing UVLO that can

prevent from miss motion at low input voltage operation, pulse by

pulse current limit for primary current of transformer, remote off circuit

that can stop the entire motions by the external voltage, the over

saturate protection circuit that stops the output by detecting the

saturated state of the transformer.

■ FEATURES
