Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Shenzhen Mingjiada Electronics Co., Ltd. introduces the Texas Instruments LM5155QDSSRQ1 AEC-Q100 compliant 2.2MHz wide input voltage, 1.5A MOSFET driver, non-synchronous boost controller for automotive and portable battery applications.

Product Features:

AEC-Q100 compliant:

- Temperature class 1: -40°C to +125°C   

Wide input operating range:

- 3.5V to 45V operating range   

- 2.97V to 16V when BIAS = VCC   

- Minimum boost supply voltage of 1.5V with BIAS greater than or equal to 3.5V   

- Input transient protection up to 50V   

Low battery consumption:

- Low shutdown current (I_Q ≤ 2.6µA)   

- Low operating current (I_Q ≤ 480µA)   

Small size and low cost:

- Maximum switching frequency of 2.2MHz   

- 12-pin WSON package (3mm × 2mm) with wettable side and non-wettable side options   

- Integrated error amplifier supports primary-side voltage regulation (flyback) without an optocoupler   

- Minimised downstroke during start-up (start-stop applications)   

High efficiency and low power consumption:

- 100mV ±7% low current limit threshold   

- Powerful 1.5A peak standard MOSFET driver   

- Supports external VCC supply   

Avoids AM band interference and crosstalk:

- Optional clock synchronisation   

- Dynamically programmable switching frequency from 100kHz to 2.2MHz   

Integrated protection features:

- Constant peak current limit over input voltage range.   

- Optional intermittent mode short circuit protection (see device comparison table)   

- Programmable line UVLO   

- OVP protection   

- Thermal shutdown protection
