Buck converter capacitor formula
WebMay 5, 2024 · From an ideal buck converter with no input filter, the inductor ripple current is ( (Vg - V) * D * Ts) / (2 * L). This should be the same for L2 in the above circuit. If VC1 = Vg then I would calculate the inductor ripple in L2 as: Eq. 1 : ( (Vg - V) * D * Ts) / (2 * L2) It's the same as before! But this answer is wrong. The correct answer is: e WebAbout. ★ Analog/Power Management IC Design Engineer. ★ Technical Skills: • Analog IC Fundamentals: Single-Stage + Differential Amplifiers, Feedback and Control Theory. • Data Converters: SAR-ADC (sample&hold, capacitive DAC, comparator, etc.) • Switched-Mode/DC-DC Converter (Buck, Boost, Buck-Boost) + Control Architectures (PWM ...
