NJM2368

NJM2368 SWITCHING REGULATOR CONTROL IC FOR FLYBACK ■GENERAL DESCRIPTION The NJM2368 is a high speed switching regulator control IC which can operate at low voltage. It uses a totempole output circuit , so that it can drive an external Bipolar Transistor directly. It is suitable for applications of flyback type switching regulation of up to 10W. ■PACKAGE OUTLINE NJM2368D ( DIP8 ) NJM2368M ( DMP8 ) ■FEATURES ● Operating Voltage (3.6V ~ 32V) ● Wide Oscillator Range (5kHz ~ 350 kHz) ● Soft-Start function. ● Under Voltage Lockouts (U.V.L.O.) ● Bipolar Technology ● Package Outline DIP8, DMP8, SOP8 JEDEC 150mil, SSOP8 ■BLOCK DIAGRAM NJM2368E ( SOP8 ) NJM2368V ( SSOP8 ) REF 8 VREF U.V.LO CT 7 30uA OSC CS 6 L.O 0.52V ER⋅AMP PW M S.C.P V+ 5 500Ω PIN FUNCTION 1.
