LM3475 Datasheet Hysteretic Pfet Buck Controller

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM3475 Hysteretic PFET Buck Controller October 2004 LM3475 Hysteretic PFET Buck.

General Description

The LM3475 is a hysteretic P-FET buck controller designed to support a wide range of high efficiency applications in a very small SOT23-5 package.

The hysteretic control scheme has several advantages, including simple system design with no external compensation, stable operation with a wide range of components, and extremely fast transient response.

Hysteretic control also provides high efficiency operation, even at light loads.
