MAX17244

MAX17244 EVALUATION KIT AVAILABLE 3.5V–36V, 2.5A, Synchronous Buck Converter With 28µA Quiescent Current and Reduced EMI General Description The MAX17244 high-efficiency, synchronous step-down DC-DC converter with integrated MOSFETs operates over a 3.5V to 36V input voltage range with 42V input transient protection. The device can operate in dropout condition by running at 98% duty cycle. This converter delivers up to 2.5A and generates fixed output voltages of 3.3V/5V, along with the ability to program the output voltage between 1V to 10V. The MAX17244 uses a current-mode control architecture. The device can operate in the 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 switching frequency. PFM operation disables negative inductor current and additionally skips pulses at light loads for high efficiency. Under light-load applications, the e...
