ISL65426MREP
Enhanced Product (EP) 6.0A Dual
Synchronous Buck Regulator with
Integrated MOSFETs
The ISL65426MREP is a high efficiency dual output
monolithic synchronous buck converter operating over an
input voltage range of 2.5V to 5.5V. This single chip power
solution provides two output voltages which are selectable or
externally adjustable from 1.2V to 80% of the supply voltage
while delivering up to 6.0A of total combined output current
when used at T
J
of +125°C or less. The two PWMs are
synchronized 180° out of phase reducing the RMS input
current and ripple voltage.
The ISL65426MREP switches at a fixed frequency of 1MHz
and utilizes current-mode control with integrated
compensation to minimize the size and number of external
components. The internal synchronous power switches are
optimized for good thermal performance, high efficiency,
and eliminate the need for an external Schottky diode.
A unique power block architecture allows partitioning to
support one of four configuration options. One master
power block is associated with each synchronous converter
channel. Four floating slave power blocks allow the user to
assign them to either channel. Proper external
configuration of the power blocks is verified internally prior
to soft-start initialization.
Independent enable inputs allow for synchronization or
sequencing soft-start intervals of the two converter
channels. A third enable input allows additional sequencing
for multi-input bias supply designs. Individual power good
indicators (PG1, PG2) signal when output voltage is within
regulation window.
The ISL65426MREP integrates protection for both
synchronous buck regulator channels. The fault conditions
include overcurrent, undervoltage, and IC thermal monitor.
High integration contained in a thin Quad Flat No-lead
(QFN) package makes the ISL65426MREP an ideal choice
to power many of today’s small form factor applications. A
single chip solution for large scale digital ICs, like field
programmable gate arrays (FPGA), requiring separate core
and I/O voltages.
