In typical LiDAR receivers, photodiodes detect incoming photons and simultaneously generate substantial current that translates into voltage signals. To minimize the detection intervals, photodiode voltage supply must recover rapidly from current transient events. Maintaining a high voltage with minimal ripple is also crucial for enhancing sensitivity and signal-to-noise ratio (SNR). To address these requirements in battery or USB-powered systems, a step-up DC-DC converter with high voltage (HV) (>15V), fast transient response (hundreds of ns), high efficiency and
