DP3119B
Description
- Features
DP3119B integrates a high efficiency synchronous step-down switching regulator, which includes a 36V, 76mΩ high side and a 36V, 52mΩ low side MOSFETs to provide 3.1A continuous load current over 6.5V to 36V wide operating input voltage with 33V input over voltage protection. Peak current mode control provides fast transient responses and cycle-by-cycle current limiting.
DP3119B has configurable line drop pensation, configurable charging current limit. CC/CV mode control provides a smooth transition between constant current charging and constant voltage charging stages. Built-in soft-start prevents inrush current at power-up.
