le) optimizes their physical dimensions. Synchronous rectification and pulse skipping mode for the buck sections optimise the overall efficiency over a wide load current range (96% efficiency @1A/5.1V and 93% efficiency @ 0.05A/5.1V. The two high performance PWM controllers for +3.3V and +5.1V lines are monitored for overvoltage, undervoltage and overcurrent conditions. On detection of a fault, a POWER GOOD signal is generated and a specific shutdown procedure takes place to prevent physical damage and data corruption. A disable function allows to manage the output power sections separately, o... |
