   产品概述 返回TOPneK嘉泰姆

The CXLB7411 is highly-integrated switch-mode system power management devices for smart power bank application and regulated output voltage including 5V /9V /12V. Its low impedance power switch optimizes switch-mode operation efficiency, reduces MOS power consumption. The USB D+/D- data line makes the device protocol handshake to set suitable output voltage to do fast charging function. The chip is compliant with QC 2.0 class A specifications with Max. output current up to 3A at 5V. Besides the converter includes two switch MOSFETs as synchronous boost converter. So no external Schottky diode is required and could get better efficiency near 92%. Other features include built-in soft start, thermal shutdown protection, under-voltage lockout (UVLO), and short circuit protection function, which can shut off the device if output voltage reaches below 1.5V. The CXLB7411 is available in a space-saving SOP-8 (Exposed Pad) package with an exposed pad.
