POWER MANAGEMENT  
Features  
Description  
„
„
„
Input voltage — 0.7V to 4.5V  
The SC120 is a high efficiency, low noise, synchronous  
step-up DC-DC converter that provides boosted voltage  
levels in low-voltage handheld applications. The wide  
input voltage range allows use in systems with single  
NiMH or alkaline battery cells as well as in systems with  
higher voltage battery supplies. It features an internal  
1.2A switch and synchronous rectifier to achieve up to  
94% efficiency and to eliminate the need for an external  
Schottky diode. The output voltage can be set to 3.3V  
with internal feedback, or to any voltage within the speci-  
fied range using a standard resistor divider.  
Minimum input startup voltage — 0.865V  
Output voltage — fixed at 3.3V; adjustable from 1.8V  
to 5.0V  
Peak input current limit — 1.2A  
Output current at 3.3 VOUT — 80mA with VIN = 1.0V,  
190mA with VIN = 1.5V  
Efficiency up to 94%  
Internal synchronous rectifier  
Switching frequency — 1.2MHz  
Automatic power save  
Anti-ringing circuit  
Operating supply current (measured at OUT) — 50μA  
Shutdown current — 0.1μA (typ)  
No forward conduction path during shutdown  
Available in ultra-thin 1.5 × 2.0 × 0.6 (mm)  
MLPD-UT-6 and SOT23-6 packages  
Lead-free and halogen-free

„
The SC120 operates in Pulse Width Modulation (PWM)  
mode for moderate to high loads and Power Save Mode  
(PSAVE) for improved efficiency under light load condi-  
tions. It features anti-ringing circuitry for reduced EMI in  
noise sensitive applications. Output disconnect capability  
is included to reduce leakage current, improve efficiency,  
and eliminate external components sometimes needed to  
disconnect the load from the supply during shutdown.  
„
„
WEEE and RoHS compliant  
Applications  
Low quiescent current is obtained despite a high 1.2MHz  
operating frequency. Small external components and the  
space saving MLPD-UT-6, 1.5×2.0×0.6 (mm) package, or  
low cost SOT23-6 package, make this device an excellent  
choice for small handheld applications that require the  
longest possible battery life.
