MAX1953EUB Description

Short technical summary and product information.

MAX1953EUB is a current-mode PWM buck controller designed for step-down DC-DC conversion. The device operates with a supply voltage ranging from 3V to 5.5V and switches at a fixed 1MHz frequency, enabling compact external component selection. It features synchronous rectification and a maximum duty cycle of 89%, supporting efficient down-conversion in low-voltage systems.

 

The controller provides a single positive output configured as a transistor driver. Current limit control helps protect the circuit during overload conditions. With an operating temperature range of -40°C to +85°C, it suits industrial and consumer applications.

 

This surface-mount device is offered in a 10-TFSOP or 10-MSOP (0.118 inch, 3.00mm width) package, with a supplier device package option of 10-uMAX. The compact footprint is suitable for space-constrained power supply designs.
