The MAX1745EUB is a high-voltage, step-down DC-DC controller designed for efficient power conversion. It is capable of handling input voltages up to 36V and utilizes a proprietary current-limited control scheme for excellent light- and full-load efficiency, exceeding 90% in some configurations.
This controller features a maximum switching frequency of 330kHz, enabling the use of small external components, making it suitable for space-critical applications. The MAX1745 variant offers an adjustable output voltage range from 1.25V to 18V, generated through an external feedback network. Operation to 100% duty cycle allows for low dropout voltage.
The MAX1745EUB is housed in a compact 10-pin µMAX package, designed for surface mounting. Its features make it suitable for applications such as automotive electronics, telecom systems, wall-cube-powered devices, industrial control systems, and Firewire/IEEE1394 interfaces.
