PRODUCTION DATA
The control loop bandwidth measures how quickly the device responds to a change in output voltage. With the TPSM8287A1xM external compensation, the loop bandwidth is adjustable to balance the tradeoff of a fast response versus stability and ringing. The RComp1 resistor and output capacitance are the primary means of adjusting the loop bandwidth.
TI recommends setting the target loop bandwidth to 200kHz for a simple design. If strong load transients are expected in the application, the target bandwidth can be set as high as ¼ of the switching frequency. A target bandwidth of 300kHz is used for this example design.
