Subject: [SI-LIST] Minimum ENA frequency for Power control loop stability
measurement
Hi folks
trying to order an ENA that can be used to measure power control loop stability
for Switching regulators whose PWM frequency is 1-4 MHz.
What is the minimum frequency range the ENA should support for this task ?
thanks
Praveen
