25 | The device utilizes digital technology to implement all control and power management | |
26 | functions to provide maximum flexibility and performance. The NVM is embedded to store | |
27 | custom configurations. The PM6764TR device features up to 4-phase programmable operation. | |
28 | ||
29 | The PM6764TR supports power state transitions featuring VFDE, and programmable DPM | |
30 | maintaining the best efficiency over all loading conditions without compromising transient | |
31 | response. The device assures fast and independent protection against load overcurrent, | |
32 | under/overvoltage and feedback disconnections. |
