LTC7149IUFD#PBF
Brand: Analog Devices
The LTC7149IUFD#PBF is a 60 V synchronous monolithic buck regulator that generates a regulated negative output — down to -28 V — directly from a single positive input rail, delivering up to 4 A of inductor current. A resistor-programmable, synchronizable 300 kHz to 3 MHz switching frequency lets designers balance efficiency, size and noise across automotive, industrial and telecom negative-rail applications.

Power Features & Applications
- Synchronous monolithic switches generate a regulated negative output directly from a positive input rail
- VOUT adjustable from 0 V to -28 V covers most negative-rail bias and amplifier-supply needs
- Resistor-programmable 300 kHz to 3 MHz switching frequency trades efficiency against external component size
- Synchronizable switching frequency avoids beat-frequency noise in multi-rail systems
- Wide 3.4 V to 60 V input range covers automotive, industrial and telecom bus voltages
- 28-lead QFN with exposed pad improves thermal performance for 4 A output designs
