ZHCSNR7A March 2022 – August 2022 TPS55289
PRODUCTION DATA
The TPS55289 implements both peak current and average inductor current limit. The average current mode control loop uses the current sense information at the high-side MOSFET of the boost leg to clamp the maximum average inductor current to 8 A (typical).
Besides the average current limit, a peak current limit protection is implemented during transient to protect the device against overcurrent conditions beyond the capability of the device.
