LTC3532EMS#PBF

Voltage Regulators - DC DC Switching Regulators Overview

The LTC3532EMS#PBF is a high-efficiency, synchronous Buck-Boost DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 2.4 V to 5.5 V and provides a single adjustable output ranging from 2.4 V to 5.25 V. The device supports a maximum output current of 500 mA and features a switching frequency between 300 kHz and 2 MHz. It includes shutdown functionality and operates within a temperature range of -40°C to +85°C. Packaged in a 10-lead MSOP (0.118 inch width), it is designed for applications requiring stable power delivery across varying input conditions.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Synchronous Buck-Boost topology maintains regulation when input voltage is above, below, or equal to the output voltage.
• Adjustable output voltage allows flexibility for various load requirements within the specified range.
• Integrated shutdown mode reduces quiescent current consumption during inactive periods.

Voltage Regulators - DC DC Switching Regulators Applications

• Portable battery-powered devices requiring stable voltage despite battery discharge curves
• Systems operating with single-cell lithium-ion or alkaline batteries
