LTC1046IS8 Description

Short technical summary and product information.

The LTC1046IS8 from Linear Technology (LT) is a versatile monolithic CMOS switched capacitor voltage converter. It is designed to provide higher output current than the ICL7660 and LTC1044, making it suitable for applications requiring up to 50mA.

 

This device supports multiple voltage conversion functions, including inversion (VOUT = – VIN), division (VOUT = VIN/2), and multiplication (VOUT = ±nVIN). It features a wide operating supply voltage range from 1.5V to 6V and boasts high conversion efficiencies, with a minimum of 97% open-circuit voltage conversion efficiency and 95% power conversion efficiency.

 

The LTC1046IS8 is pin-for-pin and functionally compatible with the ICL7660 and LTC1044, offering 2.5 times the output drive capability. It is available in an SO-8 package, suitable for surface mount applications.

 

Key electrical specifications include a maximum output current of 50mA, a maximum ROUT of 35Ω, and a low no-load supply current of 300μA at 5V. The operating temperature range for the LTC1046IS8 variant is -40°C to 85°C.
