SC121
Not Recommended for New Designs
The SC121 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.
Features
- Input voltage — 0.7V to 4.5V
- Minimum start-up voltage — 0.85V
- 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
- Forced PWM operation at all loads
- Efficiency up to 94%
- Internal synchronous rectifier
- No forward conduction path during shutdown
- Switching frequency — 1.2MHz
- Soft-start startup current limiting
- Shutdown current — 0.1μA (typ)
