NJM2367
5.5A HIGH POWER DC/DC CONVERTER CONTROLLER IC
sGENERAL DESCRIPTION
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.
