The MAX17552AUB+ is a 60V, 100mA, ultra small, high efficiency, synchronous step down DC to DC converter with 22µA no-load supply current in 10 pin µMAX package. 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%. The device employ a peak-current-mode control architecture with a MODE pin that can be used to operate the device in pulse-width modulation (PWM) or pulse frequency modulation (PFM) control schemes. PWM operation provides constant frequency operation at all loads and is useful in applications sensitive to variable switching frequency. PFM operation disables negative inductor current and additionally skips pulses at light loads for high efficiency. The converters consume only 22µA of no-load supply current in PFM mode. The low resistance, on-chip MOSFETs ensure high efficiency at full load and simplify PCB layout.
