MAXIM Integrated - 100mA MAX17552, 1.7A MAX17505, 3.5A MAX17504
1. 500mA to 3.5A synchronous buck converters with 4.5V to 60V input range, so you stock fewer regulators;
small and simple. Bye-bye, Schottky. (MAX17501-5)
2. 100mA synchronous buck converter uses just 22µA of no-load supply current; full 4V to 60V input range;
small and simple. Bye-bye, Schottky. (MAX17552)
3. 300mA synchronous buck converter is the industry's smallest high-voltage synchronous buck regulator;
4.5V to 60V input range; small and simple. Bye-bye, Schottky. (MAX15062)

Product Benefits
high-efficiency, high-voltage, synchronous step-down DC-DC converters with integrated MOSFETs operate over a 4V to 60V input voltage range. The converters can deliver output current up to 100mA at output voltages of 0.8V to 0.9 x VIN. The output voltage is accurate to within ±1.75% over the -40°C to +125°C temperature range.
Specifications
This family of synchronous buck converters is designed to save space on your board and time in your week. Up to 65%* smaller than non-synchronous products, they're also more reliable—up to four times* the running life—due to higher efficiency with less heat dissipation. And because they need fewer discrete components, they're a lot simpler to work with.
