NJM2360 DC/DC CONVERTER CONTROL IC ■ GENERAL DESCRIPTION The NJM2360 is a DC to DC converter control IC. Due to the internalization of a high current output switch, 1.5A switching operations are available. The NJM2360 is designed to be incorporated in step-up, step-down and inverting applications with a minimum number of external components. Output current is limited by an external resistor. ■ FEATURES • Output Switch Current 1.5A(MAX) • Operating Voltage 2.5V* to 40V • Internal Over Current Limit Circuit • Supply Voltage V+ 2.5V* to 40V • Output Voltage • Oscillator Frequency • Package Outline VOR fOSC 1.25V to 40V 100Hz to 100kHz DIP8, DMP8 *Ta =25°C. At low temperature, the minimum voltage is 3.0V. ■ PIN CONFIGURATION ■ PACKAGE OUTLINE NJM2360D NJM [ ... ]
