Description
The STOD1412 is a dual DC-DC converter capable of providing a positive and negative voltage from a positive input voltage ranging from 2.7 V to 5.5 V. It integrates two complete power stages, one step-up and one inverting, each of which need just one inductor, and input and output capacitor.
FEATUREs
■ 2.7 V to 5.5 V input voltage range
■ 120 mA max output current for each converter
■ Output voltages:
– Step-up from 4.3 V to 6.0 V
– Inverting from -8.0 V to -2.0 V
■ Synchronous rectification for both DC-DC converters
■ Efficiency:
– 80% IO = 10 mA - 30 mA
– 85% IO = 30 mA - 120 mA
■ 1.3 MHz PWM mode control
■ Shutdown mode with Enable pin
■ Inrush current protection
■ Adjustable output voltages
■ True shutdown mode
■ Less than 1 µA current consumption in shutdown mode
■ Over-temperature protection
■ Package: 16 pin - QFN 3X3
■ Temperature range: -40°C to 85°C
APPLICATIONs
■ Active matrix organic LED power supplies
■ Mobile phones
■ PDAs
■ Camcorders
■ Digital still cameras
