The LMG5126 is a stackable multiphase synchronous boost converter. The device provides a regulated output voltage for lower or equal input voltage also supporting VI to VOUT bypass mode to save power. Up to 4 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 startup as the internal VCC supply is automatically switched from VBIAS to VOUT for VBIAS < 6.5V. The fixed switching frequency is set between 300kHz and 2.5MHz via 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.
