BCT9001

Charge Pump DC/DC Converter with Programmable Regulated Voltage

General Description

The BCT9001 is a general purpose charge pump DC/DC converters which generates a fixed regulated output voltage from 2.7V to 3.6V which is adjustable by the external resistor divider. The BCT9001 can accept wide input voltage ranging from 1.0V to 4.0V where applications using standard batteries, standard Li-ion or NiMH/NiCd rechargeable batteries are preferred.

The BCT9001 will step up the output voltage automatically from lower input voltage. In additional; they can also regulate the output voltage when the input voltage is greater than the output voltage. A variety of switching control will be adapted by an internal input adaptation circuitry which will generate a required programmable voltage with respect to the input voltage level.

A high efficiency and space saving DC/DC converter can be easily built by incorporating external SMT ceramic capacitors. No choke coil and schottky diode are required.
