Each TPS7H500x-SEP controller uses a transconductance error amplifier. The error amplifier compares the VSENSE pin voltage to the lower of the SS pin voltage or the internal 0.613-V voltage reference. The transconductance of the error amplifier is 1800 µA/V during normal operation. The frequency compensation network is connected between COMP pin and AVSS. The error amplifier DC gain is typically 10,000 V/V.
