NJM2360A
HIGH PRECISION DC/DC CONVERTER CONTROL IC
■ GENERAL DESCRIPTION
The NJM2360A is a control circuit containing the primary functions
required for DC to DC CONVERTOR.
This device consist of high precision reference, comparator
controlled duty cycle oscillator with an active current limit circuit,
driver and high current output switch.
This IC was specifically designed to be incorporated in step-up,
step-down and inverting applications with a minimum number of
external components. This IC is designed to be ±5% output voltage
by using precision 1% resistance on external detected resistance.
