Features, Applications

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.


Power dissipation: 24W at VIN = 1.5V, VOUT = 3.0V, IOUT = 100A Start-up input voltage: 0.9V (max) = 30k Output voltage: to 3.3V, available in 0.1Vstep High efficiency: 85% at VIN = 1.5V, VOUT = 3.0V, IOUT = 1mA Low ripple voltage Package: SOT89-3
