uP1605

uP1605 Compact Dual-Phase Synchronous-Rectified Buck Controller General Description The uP1605 is a compact dual-phase synchronousrectified Buck controller specifically designed to deliver high quality output voltage for high power applications. This part is capable of delivering up to 60A output current thanks to its embedded bootstrapped drivers that support 12V + 12V driving capability. The uP1605 features configurable gate driving voltage for maximum efficiency and optimal performance. The built-in bootstrap diode simplifies the circuit design and reduces external part count and PCB space. The output voltage is precisely regulated to the reference input that is dynamically adjustable by external voltage divider. The uP1605 adopts DCR current sensing technique for over current protection and droop control. The adjustable current balance is achieved by RDS(ON) current sensing technique. This part features comprehensive protection functions including over current protection, input/o...
