Patent ID: 7394305

Claim:
A regulator, connected to regulator voltages including a pump voltage from a high-voltage pump and a load voltage for a load, for controlling the pump voltage to form the load voltage, said pump voltage providing a rising load voltage during a rise time when said high-voltage pump is enabled by an enable signal and a falling load voltage during a fall time when said high-voltage pump is disabled by said enable signal comprising: a switch connected between the load voltage and a circuit voltage and having a switch gate for receiving a gate signal for controlling conduction by said switch, a control circuit for providing said gate signal, said control circuit including, a ramp unit, connected between a regulator voltage and ground, providing a ramp current for controlling the rising load voltage during said rise time, a discharge unit, connected between the load voltage and the circuit voltage, for controlling the falling load voltage during said fall time, wherein said discharge unit and said ramp unit operate independently to independently control the rising load voltage and the falling load voltage.
