1. A voltage converter, comprising:
a power stage configured to generate an output voltage (Vo) and an output current (Io) based on a switching frequency (fs);
a primary control loop configured to vary the switching frequency (fs) in response to an on-time value code (Ton_code); and
a secondary control loop configured to generate the Ton_code;
wherein the secondary control loop is configured to set a T_high threshold and a T_low threshold.
