Maxim MAX1953/MAX1954/MAX1957 Datasheet
The MAX1953, MAX1954, and MAX1957 are a family of low‑cost, high‑frequency, current‑mode PWM buck controllers designed for applications where size and cost are critical. They operate from a 3 V to 5.5 V input range and deliver up to 10 A (MAX1953) or 25 A (MAX1954) of output current.
Key features include fixed‑frequency switching (1 MHz for MAX1953, 300 kHz for MAX1954/1957), internal soft‑start, thermal overload protection, and undervoltage lockout. The devices are offered in a compact 10‑pin UMAX package and are suited for printers, scanners, graphics cards, microprocessor core supplies, and telecom power distribution.
