产品概述
The SM72485 step-down switching regulator features all of the functions required to
implement a low cost, efficient, Buck bias regulator. This high voltage regulator contains an 100-V
N-channel buck switch. The device is easy to implement and is provided in the VSSOP and the
thermally enhanced WSON package. The regulator is based on a control scheme using an on-time
inversely proportional to VIN. This feature allows the operating frequency
to remain relatively constant. The control scheme requires no loop compensation. An intelligent
current limit is implemented with forced off-time, which is inversely proportional to
VOUT. This scheme ensures short circuit control while providing minimum
foldback. Other features include: Thermal shutdown, VCC undervoltage
lockout, gate drive undervoltage lockout, maximum duty cycle limiter, and a precharge
switch.
