Fet sensing programmable active droop for power supplies |
摘要 |
A switching regulator having an active droop voltage generator that is responsive to a drain-to-source current of a current sense element within the switching regulator. A droop signal affects the duty cycle of a pulse-width modulated signal generated by control loop. The pulse width modulated signal is fed back to the input of the switching regulator to control the amount of droop. The droop voltage generator is programmable, having a selectable gain-setting resistor.
