company blog about Texas Instruments: LM5155QDSSRQ1 2.2MHz Wide-Input Asynchronous Boost, SEPIC, Flyback Controller

Mingjiada Electronics sells Texas Instruments: LM5155QDSSRQ1 2.2MHz Wide Input Non-Synchronous Boost, SEPIC, Flyback Controller for Automotive Applications.

LM5155QDSSRQ1 Descriptions:

The LM5155QDSSRQ1 is an asynchronous boost controller with wide input range using peak current mode control. The device can be used in boost, SEPIC, and flyback topologies. The M5155x-Q1 can be powered by a single battery (2.97V minimum) if the BIAS pin is connected to the VCC pin. If the BIAS pin voltage is higher than 3.5V, the device can use an input supply voltage as low as 1.5V.

LM5155QDSSRQ1 Features:
