LT3502AIMS#PBF

LINEAR TECHNOLOGY  LT3502AIMS#PBF  直流-直流开关降压逐步递减稳压器, 可调, 3V-40V输入, 800mV-36V输出, 500mA输出, MSOP-10

The is a current-mode PWM step-down DC-to-DC Converter with an internal 500mA power switch. The wide input voltage range of 3 to 40V makes the LT3502A suitable for regulating power from a wide variety of sources and including 24V industrial supplies. Its high operating frequency allows the use of tiny, inductors and capacitors, resulting in a very small solution. Constant frequency above the AM band avoids interfering with radio reception. Cycle-by-cycle current limit and frequency foldback provide protection against shorted outputs. Soft-start and frequency foldback eliminates input current surge during start-up. DA current sense provides further protection in fault conditions. An internal boost diode reduces component count.
