1 / 15 page General Description The MAX1744/MAX1745 are step-down DC-DC con- trollers 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 exter- nal components for space-critical applications. Operation to 100% duty cycle permits the lowest possi- ble 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-sav- ing 10-pin µMAX® package. ________________________Applications Automotive Electronics Telecom Systems Wall-Cube-Powered Devices Industrial Control Systems Firewire/IEEE1394 ____________________________Features o High-Voltage Operation (Up to 36V IN) o Efficiency > 90% o Output Power Capability Exceeds 50W o 10-Pin µMax Package o Low-Dropout Voltage o 100% (max) Duty Cycle o 90µA Quiescent Current o 4µA Shutdown Current o Up to 330kHz Switching Frequency o Output Voltage 5V or 3.3V (MAX1744) Adjustable 1.25V to 18V (MAX1745) o Current-Limited Control Scheme High-Voltage, Step-Down DC-DC Controllers in µMAX ________________________________________________________________ Maxim Integrated Products 1 19-1776; Rev 3; 4/09 Ordering Information PART TEMP RANGE PIN-PACKAGE MAX1744EUB+ -40 °C to +85°C 10 µMAX MAX1744AUB+ -40 °C to +125°C 10 µMAX MAX1745EUB+ -40 °C to +85°C 10 µMAX MAX1745AUB+ -40 °C to +125°C 10 µMAX MAX1745EUB/V+ -40 °C to +85°C 10 µMAX GND OUT REF VL CS MAX1744 3/5 5V 3.3V ON OFF SHDN IN VH EXT P IN 4.5V TO 36V OUT 3.3V OR 5V Typical Operating Circuit 1 + 2 3 4 5 10 9 8 7 6 IN EXT VH 3/5 (FB) ( ) ARE FOR MAX1745 ONLY.
