MAX17244 Synchronous Step-Down DC-DC Converter

Analog Devices MAX17244 Synchronous Step-Down DC-DC Converter features integrated MOSFETs and operates over a 3.5V to 36.0V input voltage range with 42.0V input transient protection. The Analog Devices MAX17244 can operate in dropout condition by running at 98% duty cycle. The converters deliver up to 2.5A and generate 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 devices can operate 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 switching frequency. PFM operation disables negative inductor current and skips pulse at light loads for high efficiency.
