The Analog Devices MAX1953EUB+T is a versatile and economical synchronous current-mode pulse-width modulation (PWM) buck controller. Designed for applications where cost and size are critical, this step-down controller operates at a fixed 1MHz switching frequency, enabling the use of smaller external components and reducing overall system cost. It accepts an input voltage range of 3V to 5.5V and can supply up to 10A of output current. The MAX1953EUB+T includes selectable current limit features to optimize performance with external MOSFETs.
This controller is available in a compact 10-pin µMAX package, suitable for surface mount applications. It features an all N-channel MOSFET design for cost-effectiveness and does not require a current-sense resistor. Internal digital soft-start is included to manage inrush current, and thermal overload protection is provided for reliability. The device also includes an input undervoltage lockout (ULVO) to ensure proper operation during power-sag conditions.
Applications for the MAX1953EUB+T include printers, scanners, graphic cards, video cards, PCs, servers, microprocessor core supplies, low-voltage distributed power systems, and telecommunications and networking equipment.
