Working Principle of LTC3526BEDC-2#TRPBF

The LTC3526BEDC-2#TRPBF utilizes the synchronous buck topology to control the output voltage and current. This topology can maintain efficiency while providing high accuracy and low power dissipation. The voltage regulation is achieved by controlling the on-time and off-time of the internal MOSFETs, and the internal error amplifier regulates the MOSFETs’ on-time. The device will enter the low-power shutdown mode when it detects a short-circuit, overcurrent or open circuit. The internal resistors are used to set the output voltage via the adjustable voltage feedback comparator. The device also has a built-in current sensing circuit which enables constant-current load operation.
