Overview
| Topology | Buck Converter |
| Input voltage | 2.5-25 V |
| Switching frequency | 1000-1400 kHz |
| IC revision | 00 |
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
- Low Power Sensors
- Portable Military Radios
- Solar Panel Post-Regulator/Charger
- Long-Life, Battery-Operated Instruments
