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.
