The SP6538X has a proprietary cable voltage
dropcompensation function. Internal random frequency
modulation to reduce system EMI.
The SP6538X integrates functions and protections of
Under Voltage Lockout (UVLO), VDD over Voltage
Protection (VDD OVP), Cycle-by-cycle Current Limiting
(OCP), Short Load Protection (SLP), On-Chip Thermal
Shutdown, VDD Clamping, etc
The SP6538X is available in SOP-7 package.
