17V Input, Dual 1A Output Synchronous Step-Down
Regulator with Ultralow Quiescent Current
Design Note 537
Haoran Wu
Introduction
The LTC В®3622 dual 1A synchronous monolithic stepdown regulator enables compact, high efficiency supplies for battery powered systems and portable devices
as well as general purpose point-of-load regulation.
The tiny 14-pin, 3mm Г— 4mm DFN package takes input
voltages from 2.7V to 17V, producing two adjustable
В±1% accurate outputs from 0.6V to VIN while delivering
up to 1A output current on both channels. The two channels can operate in phase or with 180В°
phase shift, selected by tying the PHASE pin to GND
or INTVCC. This provides users the flexibility to
separate the channelsвЂ™ switching edges to minimize
any noise coupling. There are two peak current limit
levels for the LTC3622 вЂ“ 1.8A or 1A, selected via the
ILIM pin. This selectable current limit allows smaller
size inductors in lower current designs to minimize
solution size and cost. The LTC3622вЂ™s quiescent current with both channels
enabled is as low as 5ВµA in Burst Mode В® operation
and less than 0.1ВµA in shutdown. The switching
frequency is fixed at 1MHz or 2.25MHz with a В±50%
synchronization range to an external clock. Selectable …
