ꢀ 94% Efficient at 200mA Output Current

ꢀ 16µA Quiescent Supply Current

The HWD20011/HWD2001/HWD20012 compact, high

effIciency, step-up DC-DC converters fit in small MSOP

packages. They feature a built-in synchronous rectifier,

which improves efficiency and reduces size and cost

by eliminating the need for an external Schottky diode.

Quiescent supply current is only 16µA.

ꢀ Internal Synchronous Rectifier (no external diode)

ꢀ 0.1µA Logic-Controlled Shutdown

ꢀ LBI/LBO Low-Battery Detector

The input voltage ranges from 0.7V to V

, where

OUT

can be set from 2V to 5.5V. Start-up is guaran-

ꢀ Selectable Current Limit for Reduced Ripple

te e d from 1.1V inp uts . The HWD20011/HWD2001/

HWD20012 have a preset, pin-selectable output for 5V or ꢀ Low-Noise, Anti-Ringing Feature (HWD20012)

3.3V. The outputs can also be adjusted to other volt-

ages using two external resistors.

ꢀ 8-Pin and 10-Pin MSOP Packages

ꢀ Preassembled Evaluation Kit (HWD20012EVKIT)

All thre e d e vic e s ha ve a 0.3Ω N-c ha nne l MOSFET

power switch. The HWD20011 has a 1A current limit. The

HWD2001 has a 0.5A current limit, which permits the

use of a smaller inductor. The HWD20012 comes in a

10-pin MSOP package and features an adjustable cur-

rent limit and circuitry to reduce inductor ringing.
