Analog Devices / Maxim Integrated MAX17530 Synchronous Step-Down DC-DC Converters

Analog Devices MAX17530 Synchronous Step-Down DC-DC Converters come with integrated MOSFETs and operate over a 4V to 42V input voltage range. These Analog Devices converters deliver up to 25mA current and generate output voltages from 0.8V to 0.9 x VIN. The MAX17530 converters use peak-current-mode control and can be operated in Pulse-Width Modulation (PWM) or Pulse Frequency Modulation (PFM) modes. 

The Analog Devices MAX17530 Synchronous Step-Down DC-DC Converters are available in 10-pin (3mm x 2mm) TDFN and 10-pin (3mm x 3mm) µMAX® packages.
