LTC7149 | DigiKey Daily

The LTC®7149 is a high efficiency 60V, 4A synchronous monolithic step-down regulator for inverting output applications. It incorporates a current mode architecture with user selectable internal or external loop compensation and an output voltage that is programmed with a single external resistor. The LTC7149 operates from an input voltage range of 3.4V to 60V and provides an adjustable output voltage from 0V to –28V, while delivering up to 4A of continuous output current, making it ideal for a wide range of test, measurement and industrial applications. The LTC7149’s switching frequency is user programmable from 300kHz to 3MHz, enabling the use of tiny, low cost capacitors and inductors.
