LM51571QRTERQ1 General Description

The LM51571-Q1 is a non-synchronous boost converter that incorporates a 50-V, 4.33-A power switch, making it ideal for a wide range of applications. Its flexibility allows for use in boost, SEPIC, and flyback topologies, providing designers with options for their specific requirements. The device's ability to start up from a single-cell battery with a minimum of 2.9 V makes it particularly suitable for portable and battery-powered systems. Furthermore, with the capability to operate with input supply voltages as low as 1.5 V, provided that the BIAS pin is greater than 2.9 V, the LM51571-Q1 offers versatility in various power supply designs. With its integrated power switch delivering up to 4.33 A, the LM51571-Q1 is well-suited for applications requiring high power density
