MAX1744 Datasheet (Maxim) - High-Voltage / Step-Down DC-DC Controller

MAX1744, High-Voltage / Step-Down DC-DC Controller

The MAX1744/MAX1745 are step-down DC-DC controllers capable of handling up to 36V inputs.

These parts use a proprietary current-limited control scheme for excellent light- and full-load efficiency, while their 330kHz (max) switching frequency permits small external components for space-critical appl
