The device implements a voltage-mode control with voltage feed-forward compensation that responds instantly to input voltage change. Pre-bias capability eliminates concerns about damaging sensitive loads. 7.2 Functional Block Diagram 7.3 Feature Description 7.3.1 Voltage Reference The 600-mV bandgap cell is internally connected to the non-inverting input of the error amplifier. The reference voltage is trimmed with the error amplifier in a unity gain configuration to remove amplifier offset from the final regulation voltage. The 1% tolerance on the reference voltage allows the user to design a very accurate power supply. |
