Description

The CR-F33T is a PFM step-up DC/DC converter IC and has a high efficiency.
These devices consist of a bandgap, a comparator, an oscillator, a driver, and a high current output switch.
The CR-F33T provides a higher fixed voltage from the smaller input voltage.
The CR-F33T is used for single- or dual-cell battery operation.
