Maxim Integrated MAX1745EUB
- Part Number:
- MAX1745EUB
- Manufacturer:
- Maxim Integrated
- Ventron No:
- 3752064-MAX1745EUB
- Description:
- IC REG CTRLR BUCK 10UMAX
- Datasheet:
- MAX1744-45
Description
The MAX1744/MAX1745 are high-voltage, step-down DC-DC controllers capable of handling up to 36V inputs. They utilize 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 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 18V.
The MAX1744/MAX1745 are available in a space-saving 10-pin μMAX® package.
