Mingjiada Supply ADI LTC3110 Series Bidirectional Buck-Boost DC/DC Regulator

With the accelerating adoption of supercapacitors in applications such as backup power supplies, peak power buffering, energy harvesting and industrial energy storage, bidirectional DC/DC regulators—which can operate continuously and stably when the input voltage is higher than, lower than or equal to the output voltage—are becoming key components in power supply architecture design. As a specialist electronic component supply chain service provider, Mingjiada Electronics has long supplied the LTC3110 bidirectional buck-boost DC/DC regulator from ADI (Analog Devices), offering highly integrated solutions for supercapacitor charging, balancing and backup power supply systems.

[ADI/LINEAR] LTC3110 – 2A, Bidirectional, Buck-Boost DC/DC Regulator and Charger/Balancer
The LTC3110 is a 2A bidirectional buck-boost DC/DC regulator featuring a capacitor charger and balancer. The device features a wide range of capacitor/battery voltages from 0.1 V to 5.5 V and a system backup voltage range from 1.8 V to 5.25 V, making it ideal for a wide range of backup applications utilising supercapacitors or batteries. A proprietary low-noise switching algorithm optimises efficiency, and the capacitor/battery voltage may be higher than, lower than or equal to the system output voltage. The LTC3110 is available in a thermally enhanced, flat 24-pin TSSOP package and a 4mm × 4mm QFN package.

LTC3110 Key Features:
VCAP operating range: 0.1V to 5.5V
VSYS operating range: 1.71V to 5.25V
Automatic switching from charging mode to standby mode
Programmable charging input current limits from 125mA to 2A with ±2% accuracy
±1% standby voltage accuracy
