LT1373HVCS8 Description

Short technical summary and product information.

The LT1373HVCS8 is a versatile current mode switching regulator designed for high efficiency and low power consumption. Operating at a fixed frequency of 250kHz, it utilizes a 1.5A internal switch and supports various configurations including boost, buck, flyback, forward, inverting, and Cuk.

 

Key electrical characteristics include a low supply current of 1mA at 250kHz and a shutdown current of 12µA. The device accepts an input voltage range from 2.7V to 30V, with a minimum startup voltage of 2.7V. The output voltage can be regulated from 1.245V up to 42V, with a maximum switch voltage of 42V. The maximum switch current is rated at 2A.

 

This monolithic IC integrates all necessary oscillator, control, and protection circuitry. It is housed in an 8-pin SOIC package, suitable for surface mount applications. The LT1373HVCS8 can be externally synchronized to a frequency range of 300kHz to 340kHz, offering flexibility in system design to avoid sensitive frequencies.

 

Applications for the LT1373HVCS8 include portable systems, battery-powered devices, and general DC-to-DC power conversion where efficiency and compact design are critical. Its ability to operate from low supply voltages makes it ideal for single lithium-ion cell applications.
