uP6207 Overview
Key Features
- The uP6207 integrates a 5V LDO regulator that enables it to work with a single 12V supply voltage
- It also integrates bootstrapped drivers that support 12V + 12V driving capability
- The uP6207 provides programmable 2/3-phase operation
- It also supports dynamic phase selection by PS1/2 pins that automatically switches to single/two phase operation at light load condition
- The uP6207 supports both standalone and tracking mode operation
- The output voltage is tightly regulated to local or external reference voltages
- The uP6207 extract phase current signals by RDS(ON) of low side switches for phase current balance
- It senses the output current by DCR of output inductors for load line slope setting and over current protection
- This yields both thermal balance and accurate load line adjustment
- Other features include accurate and reliable short-circuit protection, adjustable over current protection, and a delayed power OK output
