ZXSC100 Datasheet SINGLE CELL DC-DC CONVERTER

Manufacturer: Zetex (now Diodes Incorporated)

Overview: ZXSC100 SINGLE CELL DC-DC CONVERTER SOLUTION.

General Description

The ZXSC100 series is designed for DC-DC applications where step-up voltage conversion from very low input voltages is required.

These applications mainly operate from single nickel cadmium or nickel metal hydride battery cells.

The ZXSC100 devices are non-synchronous PFM, DC-DC controller ICs which drive an external transistor.
