The LM5125-Q1 is a stackable, multiphase, synchronous, boost controller. The device provides a regulated output voltage for lower or equal input voltage also supporting VI to VOUT bypass mode to save power. Two devices can be stacked with or without external clock.

VOUT can be dynamically programmed using the digital or analog ATRK/DTRK function. VI can be as low as 2.5V after start-up as the internal VCC supply is automatically switched from VBIAS to VOUT for VBIAS < 4.5V. The fixed switching frequency is set between 100kHz and 2.2MHz through a resistor on the RT pin or the SYNCIN clock. The switching modes, FPWM, or diode emulation can be changed during operation.

The implemented protections peak current limit, average input current limit, average inductor current monitor, over and undervoltage protection, or the thermal shutdown protect the device and the application.
