SM6702 series

NIPPON PRECISION CIRCUITS INC.

PFM Step-up DC/DC Converter

OVERVIEW

The SM6702 series are step-up DC/DC converter ICs, fabricated using NPC’s Molybdenum-gate CMOS pro-

cess. They incorporate reference voltage source, error ampliﬁer, oscillator, start-up circuit, PFM (Pulse Fre-

quency Modulation) control circuit into a single chip. The only external components required are a Coil, Diode

and output smoothing capacitors to form a step-up DC/DC converter. They employ PFM voltage control cir-

cuits to achieve high efﬁciency, stable constant-voltage output.
