ISL6410, ISL6410A
Data Sheet
September 17, 2004
FN9149.3
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 ±10% as an input
voltage and the ISL6410A in applications requiring 5.0V
±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
MSOP 10 lead package.
Features
• Fully Integrated Synchronous Buck Regulator
• PWM Fixed Output Voltage Options
- 1.8V, 1.5V or 1.2V with ISL6410 (VIN = 3.3V)
- 3.3V, 1.8V or 1.2V with ISL6410A (VIN = 5.0V)
• Continuous Output Current . . . . . . . . . . . . . . . . . . 600mA
• Ultra-Compact DC-DC Converter Design
• Stable with Small Ceramic Output Capacitors
• High Conversion Efficiency
• Extensive Circuit Protection and Monitoring features
- Overvoltage, UVLO
- Overcurrent
- Thermal Shutdown
• Available in MSOP and QFN packages
• QFN Package:
- Compliant to JEDEC PUB95 MO-220
QFN - Quad Flat No Leads - Package Outline
- Near Chip Scale Package footprint, which improves
PCB efficiency and has a thinner profile
• Pb-Free Packaging Available

*For tape and reel, add “-T”, “-TK” or “-T5K” suffix.
NOTE: Intersil Pb-free products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which is compatible with both SnPb and
Pb-free soldering operations. Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed
the Pb-free requirements of IPC/JEDEC J Std-020B.
