PMP7766, Non Isolated Push Pull with 9 to 16V Input and ± 2 to ± 20V Output

PMP7766, PMP7766 is a non-isolated push pull topology design. It has an input of 9 to 16V. It uses an external error amplifier to control output voltage from ± 2V to ± 20V on the fly. U20 is used to tie Vin to Vcc = 16V to regulate the voltage lower than 16V to avoid damage to Vcc pin
