ZHCSF14D March 2010 – October 2018 TPS54260
PRODUCTION DATA.
The TPS54260 has a transconductance amplifier for the error amplifier. The error amplifier compares the VSENSE voltage to the lower of the SS/TR pin voltage or the internal 0.8-V voltage reference. The transconductance (gm) of the error amplifier is 310 μS during normal operation. During the slow-start operation, the transconductance is a fraction of the normal operating gm. When the voltage of the VSENSE pin is below 0.8 V and the device is regulating using the SS/TR voltage, the gm is 70 μS.
The frequency compensation components (capacitor, series resistor and capacitor) are added to the COMP pin to ground.
