LM3475 Hysteretic PFET Buck Controller October 2004 LM3475 Hysteretic PFET Buck Controller 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 pensation, stable operation with a wide range of ponents, and extremely fast transient response. Hysteretic control also provides high efficiency operation, even at light loads. The PFET architecture allows for low ponent count as well as 100% duty cycle and ultralow dropout operation.
