PRODUCTION DATA
Each BUCK regulator includes a Current Limit to protect the internal High-Side and Low-Side Power-FETs against over-current. The High-Side Current Limit, also referred to as Forward Current Limit, is for BUCK1..4 adjustable between 2.5 A and 5.5 A with 1-A steps with register bits BUCKx_ILIM[3:0]. For BUCK5, this Forward Current Limit has selectable levels 2.5 A and 3.5 A with register bits BUCK5_ILIM[3:0].
The Low-Side Current Limit, also referred to as Negative Current Limit, has a fixed value of typical 2 A.
