Analog Devices LTC3130

Overview

Topology	Buck Converter
Input voltage	2.4-25 V
Switching frequency	1000-1400 kHz

Description

The LTC3130/LTC3130-1 are high efficiency, low noise,600mA buck-boost converters with wide VIN and VOUTranges. For high efficiency operation at light loads,Burst Mode operation can be selected, reducing the quiescentcurrent to just 1.6μA. Converter start-up is achievedfrom sources as low as 7.5μW.

Features

Regulates VOUT Above, Below or Equal to VINWide VIN Range: 2.4V to 25V <1V to 25V (Using EXTVCC Input)VOUT Range: 1V to 25VAdjustable Output Voltage (LTC3130)Four Selectable Fixed Output Voltages (LTC3130-1)1.2µA No-Load Input Current in Burst Mode® Operation (VIN = 12V, VOUT = 5V)600mA Output Current in Buck ModePin-Selectable 850mA/450mA Current Limit (LTC3130)Up to 95% EfficiencyPin-Selectable Burst Mode Operation1.2MHz Ultralow Noise PWM FrequencyAccurate RUN Pin Threshold n Power Good IndicatorProgrammable Maximum Power Point ControlIQ = 500nA in ShutdownThermally-Enhanced 20-Lead 3mm × 4mm QFN and 16-Lead MSOP Packages

Typical applications

Portable Military Radios
Low Power Sensors
Long-Life, Battery-Operated Instruments
Solar Panel Post-Regulator/Charger
