1 / 1 page  EUP3269 DS3269 Ver1.2 Aug. 2016 1 CC/CV Mode Synchronous Step-Down Converter DESCRIPTION The EUP3269 is a synchronous step-down converter capable of driving 4A continuous load with excellent line and load regulation. The EUP3269 operates in either CC (Constant Current) mode or CV (Constant Voltage) mode with an input voltage range from 8V to 30V. The EUP3269 provides programmable cable compensation by adjusting external resistor divider. External shutdown function can be controlled by pulling COMP pin to a level below 0.14V. Fault protection includes secondary cycle-by-cycle current limit, short circuit protection and thermal shutdown. Internal soft-start minimizes the inrush supply current and the output overshoot at initial startup. The EUP3269 is available in SOP-8 (EP) package. Typical Application Circuit FEATURES 8V to 30V Wide Input Operating Range 80kHz~800kHz Switching Frequency Selection CC/CV Mode Control Up to 4A Output Current +/- 1.5% Voltage Reference Accuracy +/- 4% Constant Current Accuracy Programmable Cable Compensation Internal Soft Start Single Pin to External Compensation and Shutdown Control Hiccup Short Circuit Protection Secondary Cycle-by-Cycle Current Limit Thermal Shutdown Available in SOP-8 (EP) Package RoHS Compliant and 100% Lead(Pb)-Free Halogen-Free APPLICATIONS Car Charger Portable charger applications DC/DC converters with current limited Figure 1. 150KHz Operating Frequency Application Circuit |
