SNVS239C – OCTOBER 2004 – REVISED OCTOBER 2015 LM3475 Hysteretic PFET Buck Controller
1 Features 3 Description The LM3475 is a hysteretic P-FET buck controller
designed to support a wide range of high efficiency
applications in a very small SOT-23-5 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. The PFET architecture
allows for low component count as well as 100% duty
cycle and ultra-low dropout operation. 1 Easy-to-Use Control Methodology
