Abstract: A power management integrated circuit (PMIC) can improve the ramp up speed of a boost converter with the inclusion of a controllable switch that may modify the connection of an output capacitor to reduce the ramp time as the output voltage is ramping to a desired boost setpoint. The switch may be controlled using jump start logic to switch a first plate or terminal of the output capacitor from a ground connection to a voltage supply connection. Once a threshold voltage is reached, the first plate of the capacitor may be switched from the supply voltage to ground. The PMIC may further include a quick start assembly that can drive the boost converter at a high duty-cycle.

The switch may be controlled using jump start logic to switch a first plate or terminal of the output capacitor from a ground connection to a voltage supply connection. Once a threshold voltage is reached, the first plate of the capacitor may be switched from the supply voltage to ground. In certain cases, by switching the connection of the output capacitor between ground and a supply voltage based on one or more threshold voltages or a boost setpoint, the time to ramp from an initial voltage to a desired boost setpoint may be reduced.
