ZHCSFR4C DECEMBER 2016 – October 2017 TLV62569
UNLESS OTHERWISE NOTED, this document contains PRODUCTION DATA.
The switch current limit prevents the device from high inductor current and drawing excessive current from a battery or input voltage rail. Excessive current might occur with a heavy load or shorted output circuit condition. The TLV62569 adopts the peak current control by sensing the current of the high-side switch. Once the high-side switch current limit is reached, the high-side switch is turned off and low-side switch is turned on to ramp down the inductor current with an adaptive off-time.
