SM6702 series
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.
