GENERAL DESCRIPTION
A PWM step-up DC/DC converters optimized to provide a high efficiency solution to medium power system. Selectable high switching frequency allows faster loop response and easy filtering with a low noise output. Soft-start time can be programmed with an external capacitor, which sets the input current ramp rate. Current mode control and external compensation network make it easy and flexible to stabilize the system. the devices regulates the output voltage up to 12V from either a 2cell NiMH/NiCd or a single-cell Li-ion Battery with a 1MHz fixed frequency switching. These features minimize overall solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors.
