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 process.
They incorporate reference
voltage source, error amplifier, oscillator, start-up circuit, PFM (Pulse Frequency 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 circuits to achieve high efficiency, stable constant-
voltage output.
