Mingjiada Supply ADI LTC3115 40V/2A Synchronous Buck-Boost DC/DC Converter

Shenzhen Mingjiada Electronics Co., Ltd. — Long-term supplier of ADI/LINEAR power management devices, including the LTC3115: a 40V, 2A, synchronous buck-boost DC/DC converter. This device maintains a stable output when the input voltage is higher than, lower than or close to the output voltage, making it suitable for automotive electronics, industrial control, battery-powered applications and scenarios with wide input voltage fluctuations. Mingjiada Electronics maintains stock of mainstream models and supports both small-batch samples and large-volume orders. Relying on an efficient logistics system, we ensure rapid product delivery.

[ADI/LINEAR] LTC3115 — 40V, 2A, synchronous buck-boost DC/DC converter
LTC3115-1 is a high-voltage, monolithic, synchronous buck-boost DC/DC converter. The device’s wide input and output voltage range of 2.7V to 40V makes it ideal for a wide range of automotive and industrial applications. A proprietary low-noise switching algorithm optimises efficiency when the input voltage is higher than, lower than, or even equal to the output voltage, whilst ensuring seamless transition between operating modes.
LTC3115-2 is a high-voltage, single-chip synchronous buck-boost DC/DC converter optimised for applications susceptible to rapid (<1 ms) input voltage transients. For all other applications, the LTC3115-1 is recommended. The LTC3115-2 features a wide input and output voltage range of 2.7 V to 40 V, making it ideal for a wide range of automotive and industrial power supply applications. It incorporates a proprietary low-noise switching algorithm that optimises efficiency when the input voltage is higher than, lower than or equal to the output voltage, whilst ensuring seamless transition between operating modes.
