Introduction
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 external sync pin FSYNC logic input allows the device to operate either in PFM mode for reduced current consumption or fixed-frequency FPWM (forced-PWM) mode to eliminate frequency variation to minimize EMI. Fixed-frequency FPWM mode is extremely useful for power supplies designed for RF transceivers where tight emission control is necessary. This device is available in a compact 16-pin (5mm×5mm) TQFN package with exposed pad and 16-pin TSSOP. -40°C to +85°C operation.
