The MAX17242/MAX17243 high-efficiency, synchronous step-down DC-DC converters with integrated MOSFETs operates over a 3.5V to 36V input voltage range, and can operate in drop-out condition by running at 99% duty cycle. The converters deliver up to 2A (MAX17242) and 3A (MAX17243) output current and generate fixed output voltages of 3.3V/5V, along with the ability to program the output voltage between 1V to 10V. The devices use a current-mode-control architecture and can be operated 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 operation. The low-resistance, on-chip MOSFETs ensure high efficiency at full load and simplify the layout. The devices are available in a compact 20-pin (5mm x 5mm) TQFN package with exposed pad. These parts are rated for -40°C to +85°C operation. Design Solution: Online Simulator Validates Buck Converter Output Error Budget Analysis ›
