User Manual
The MAX1953/MAX1954/MAX1957 is a family of versatile, economical, synchronous current-mode, pulse-width modulation (PWM) buck controllers. These step-down controllers are targeted for applications where cost and size are critical. The MAX1953 operates at a fixed 1MHz switching fre- quency, thus significantly reducing external component size and cost. Additionally, excellent transient response is obtained using less output capacitance. The MAX1953 operates from low 3V to 5.5V input voltage and can sup- ply up to 10A of output current. Selectable current limit is provided to tailor to the external MOSFETs’ on-resistance for optimum cost and performance. The output voltage is adjustable from 0.8V to 0.86VIN.
