TYPICAL APPLICATION
DESCRIPTION
Dual Channel 3A, 15V
Monolithic Synchronous
Step-Down Regulator
The LTC3633 is a high efciency, dual-channel monolithic
synchronous buck regulator using a controlled on-time,
current mode architecture, with phase lockable switching
frequency. The two channels can run 180° out of phase,
which relaxes the requirements for input and output ca-
pacitance. The operating supply voltage range is from 3.6V
to 15V, making it suitable for dual cell lithium-ion batteries
as well as point of load power supply applications from
a 12V or 5V supply.
The operating frequency is programmable and synchroniz-
able from 500kHz to 4MHz with an external resistor. The
high frequency capability allows the use of small surface
mount inductors and capacitors. The unique constant
frequency/controlled on-time architecture is ideal for
high step-down ratio applications that operate at high
frequency while demanding fast transient response. An
internal phase lock loop servos the on-time of the internal
one-shot timer to match the frequency of the internal clock
or an applied external clock.
The LTC3633 can select between forced continuous mode
and high efciency Burst Mode operation.
