LTM4630A
Dual 18A or Single 36A
DC/DC µModule Regulator
DESCRIPTION
The
LTM
®
4630A
is a dual 18A or single 36A output switch-
ing mode step-down DC/DC µModule
®
(micromodule)
regulator with wider V
OUT
range and higher efficiency
than LTM4630. Included in the package are the switch-
ing controllers, power FETs, inductors and all supporting
components. Operating from an input voltage range of
4.5V to 18V, the LTM4630A supports two outputs each
with an output voltage range of 0.6V to 8V, each set by a
single external resistor. Its high efficiency design delivers
up to 18A continuous current for each output. Only a few
input and output capacitors are needed. The LTM4630A
is pin compatible with the LTM4620 and LTM4620A (dual
13A, single 26A) and the LTM4630 (dual 18A, single 36A).
The device supports frequency synchronization, multi-
phase operation, Burst Mode operation and output voltage
tracking for supply rail sequencing and has an onboard
temperature diode for device temperature monitoring. High
switching frequency and a current mode architecture enable
a very fast transient response to line and load changes
without sacrificing stability.
Fault protection features include overvoltage and
overcurrent protection. The LTM4630A is offered in 16mm
