Description
The LM3485 is a high-efficiency PFET switching regulator controller designed for developing small, low-cost, switching buck regulators. Its hysteretic control architecture simplifies design, eliminating control loop stability concerns. The PFET architecture enables low component count, ultra-low dropout, and 100% duty cycle operation. Additionally, it maintains high efficiency at light loads without increasing output ripple.
Features
Easy-to-use control methodology
No control loop compensation required
Wide input range: 4.5V to 35V
Adjustable output range: 1.242V to V
High efficiency: 93%
±1.3% ( 2% over temperature) internal reference
100% duty cycle
Maximum operating frequency: >1MHz
Current limit protection
MSOP-8 package
Applications
Set-Top Box
DSL/Cable Modem
PC/Laptop
Auto PC
TFT Monitor
Battery Powered Portable Applications
Distributed Power Systems
Always On Power
