High Efficiency 1.5MHz, Step up Regulator

EC9211

General Description

Features

The EC9211 is a fixed switching frequency (1.5MHz typical),

current-mode, step-up regulator with an integrated N-channel

MOSFET. The device allows the usage of small inductors and

output capacitors for portable devices. The current-mode control

scheme provides fast transient response and good output voltage

accuracy.

●Wide 2.7V to 6V Input Voltage Range

●

Built

High Efficiency up to 90%

<1mA Quiescent Current During Shutdown

‐

in 0.2Ω

‐

‐

in Soft‐Start

●

● Current‐Mode Operation

● Stable with Ceramic Output Capacitors

The EC9211 includes under-voltage lockout, current limit, and

over-temperature shutdown preventing damage in the event of an

output overload.
