5.5A HIGH POWER DC/DC CONVERTER CONTROLLER IC

■GENERAL DESCRIPTION

■PACKAGE OUTLINE

The NJM2367 is a high power DC/DC converter controller

inducing basic function of DC/DC converter controller, which

consists precision reference voltage, fixed frequency

oscillator, high gain error amplifier, precision output switch,

cycle-by-cycle current limit, under voltage lockout, and

thermal shutdown circuit.

The NJM2367 is suitable for step-down converter with few

external parts, and realize low power stand-by mode.
