LM3475EVAL

TEXAS INSTRUMENTS  LM3475EVAL  评估板, 滞后PFET, 降压控制器

The evaluation board is provided as a tool for developing DC to DC converters based on the LM3475 IC. The LM3475 is a hysteretic PFET 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. operation, even at light loads. The PFET architecture allows for low component count as well as 100% duty cycle and ultra low dropout operation.
