LM3475
Hysteretic PFET Buck Controller
General DescriptionThe LM3475isa hysteretic P-FET buck controller designed supporta wide rangeof high efficiency applicationsina
very small SOT23-5 package. The hysteretic control scheme
has several advantages, including simple system design
withno external compensation, stable operation witha wide
rangeof components, and extremely fast transient re-
sponse. Hysteretic control also provides high efficiency op-
eration, evenat light loads. The PFET architecture allowsfor
low component countas wellas 100% duty cycle and ultra-
low dropout operation.
Features Easyto use control methodology 0.8Vto VIN adjustable output range High Efficiency (90% typical) ±0.9% (±1.5% over temp) feedback voltage 100% duty cycle capable Maximum operating frequencyupto 2MHz Internal Soft-Start Enablepin SOT23-5 package
