MAX1745 High-Voltage / Step-Down DC-DC Controller

MAX1745 Description

MAX1744/MAX1745 19-1776; Rev 4; 8/09 EVAALVUAAILTAIOBNLEKIT High-Voltage, Step-Down DC-DC Controllers in µMAX General .
The MAX1744/MAX1745 are step-down DC-DC controllers capable of handling up to 36V inputs.

MAX1745 Features

* High-Voltage Operation (Up to 36V IN)
* Efficiency > 90%
* Output Power Capability Exceeds 50W
* 10-Pin µMax Package
* Low-Dropout Voltage
* 100% (max) Duty Cycle
* 90µA Quiescent Current
* 4µA Shutdown Current
* Up to 330kHz

MAX1745 Applications

* Operation to 100% duty cycle permits the lowest possible dropout voltage. The MAX1744 contains an internal feedback network that provides a pin-selectable output voltage of either 3.3V or 5V. The MAX1745 uses an external feedback network to generate an adjustable output voltage between 1.25V and 18
