SM6702 series

PFM Step-up DC/DC Converter

NIPPON PRECISION CIRCUITS INC.

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.

FEATURES

^ꢀPower dissipation : 24 µW at V = 1.5 V, V

= 3.0 V, I

= 100 µA

OUT

^ꢀStart-up input voltage : 0.9 V (max) at R = 30 kΩ

^ꢀOutput voltage : 2.2 V to 3.3 V, available in 0.1 Vstep

^ꢀHigh efﬁciency : 85% at V = 1.5 V, V

= 3.0 V, I = 1 mA

OUT

^ꢀLow ripple voltage

^ꢀPackage : SOT23-3, SOT89-3

APPLICATIONS

^ꢀPDA, Mobile IT equipment

^ꢀDigital Stil Camera

^ꢀPager

^ꢀConstant-voltage sources for battery-operated equipment

^ꢀLocal voltage sources
