uP1537
High Performance, Single Synchronous Step-Down Controller for Notebook Power Supply
General Description
Features
The uP1537 is a high-efficiency, single synchronous buck controller suitable for low output voltage point-of-load applications in notebook computers and similar digital consumer applications. The proprietary RCOTTM technology provides fast transient response and high noise immunity. It supports ceramic output capacitors. An advantage of this control scheme is that it does not require an external phase compensation network, helping the designer with ease-of-use and realizing low external component count configuration. This combination is ideal for building modern low duty ratio, ultra-fast load step response DC-DC converters. The output voltage ranges from 0.7 V to 2.
