- Adjustable 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 Mode
- Pin-Selectable 850mA/450mA Current Limit (LTC3130)
- Up to 95% Efficiency
- Pin-Selectable Burst Mode Operation
- 1.2MHz Ultralow Noise PWM Frequency
- Accurate RUN Pin Threshold n Power Good Indicator
- Programmable Maximum Power Point Control
- IQ = 500nA in Shutdown
- Thermally-Enhanced 20-Lead 3mm × 4mm QFN and 16-Lead MSOP Packages
The LTC3130/LTC3130-1 are high efficiency, low noise, 600mA buck-boost converters with wide VIN and VOUT ranges. For high efficiency operation at light loads, BurstMode operation can be selected, reducing the quiescent current to just 1.6µA. Converter start-up is achieved from sources as low as 7.5µW.
TheLTC3130/LTC3130-1 employ an ultralow noise, 1.2MHz PWM architecture that minimizes solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors. Built-in loop compensation and soft-start reduces external parts count and simplifies the design. Features include an accurate RUN comparator threshold to allow predictable regulator turn-on and a maximum power point control (MPPC) capability that ensures maximum power extraction from non-ideal sources such as photovoltaic panels. The LTC3130-1 includes an internal voltage divider to provide four selectable fixed output voltages.
Additional features include a power good output, an external VCC input and thermal shutdown.
The LTC3130 and LTC3130-1 are available in thermally-enhanced 20-lead 3mm × 4mm QFN and 16-lead MSOP packages.
