MAX17532ATB+T

The MAX17532ATB+T is an ultra small, high-efficiency, synchronous step-down DC to DC converter with 22µA no-load supply current in 10 pin TDFN package. This 42V The converter can deliver up to 100mA and generates output voltages from 0.8V up to 0.9 x VIN. The feedback (FB) voltage is accurate to within ±1.75% over -40°C to +125°C. It uses peak current mode control and can be operated in pulse-width modulation (PWM) or pulse frequency modulation (PFM) modes. It reduces external components and total cost such as no schottkys synchronous, internal compensation for any output voltage, built-in soft-start and all-ceramic capacitors, compact layout. It reduces number of DC-DC regulators to stock. It is typically used at industrial sensors and process control, high voltage LDO replacement, battery-powered equipment, HVAC and building control.
