Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

LM5155QUDSSRQ1 is a wide input range, non-synchronous boost controller that uses peak current mode control. The device can be used in boost, SEPIC, and flyback topologies.

Product Features

Wide input operating range for car and portable battery applications

– 3.5-V to 45-V Operating range

– 2.97-V to 16-V When BIAS = VCC

– Minimum boost supply voltage 1.5 V when BIAS ≥ 3.5 V

– Input transient protection up to 50 V

Minimized battery drain

– Low shutdown current (IQ ≤ 2.6 µA)

– Low operating current (IQ ≤ 480 µA)

Higher efficiency with low-power dissipation

– 100-mV ±7% Low current limit threshold

– Strong 1.5-A peak standard MOSFET driver

– Supports external VCC supply

Avoid AM band interference and crosstalk

– Optional clock synchronization

– Dynamically programmable switching frequency from 100 kHz to 2.2 MHz

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?
