Rev 3.00
September 17, 2004 Single Synchronous Buck Regulators with Integrated FET
The ISL6410, ISL6410A are synchronous current-mode
PWM regulators designed to provide a total DC-DC solution
for microcontrollers, microprocessors, CPLDs, FPGAs, core
processors/BBP/MAC, and ASICs. The ISL6410 should be
selected for applications using 3.3V В±10% as an input
voltage and the ISL6410A in applications requiring 5.0V
В±10%.
These synchronous current mode PWM regulators have
integrated N-and P-Channel power MOSFETs and provide
pre-set pin programmable outputs. Synchronous rectification
with internal MOSFETs is used to achieve higher efficiency
and a reduced external component count. The operating
frequency of 750kHz typical allows the use of small inductor
and capacitor values. The device can be synchronized to an
external clock signal in the range of 500kHz to 1MHz. A
power good signal “PG” is generated when the output
voltage falls outside the regulation limits. Other features
include overcurrent protection and thermal overload
shutdown. The ISL6410, ISL6410A are available in an …
