Buck Converter Basics

• Alternately turn on Q1 and Q2 so Average VSW = VOUT

• Average VSW is set by duty cycle using negative feedback

• Feedback can use VOUT or VOUT & IL defines control mode

• Feedback then adjusts one of either (ton or toff) or tsw, holding the other constant defines control

scheme

• Control Mode +Control Scheme e.g. Fixed Frequency Voltage Mode Control

• Lossless in theory 7

Temporal Aspect of Control

• Identical duty cycle can be achieved by modulating on time, off time or frequency

• Leading or trailing edges can be modulated

• All these methods can be used to control voltage, current or both

– “Fixed Frequency, Leading Edge, Voltage Mode Control”

– “Constant On Time Current Mode Control” 8

Estimating Current Imbalance

• Current Imbalance due to

– On time mismatch propagation delays, Cgs variations, Rg variations etc

– Resistance mismatch -> Process variation, PCB routing, thermal environments

• Duty cycle must be identical at the inductors for volts-sec balance!

• Increase 𝐾𝑇𝑖 to reduce 𝐼𝑖 and hence

• Thermal balance is open loop and not

Thermal Balance: System-Level Trade-Off

• Power stage temperature is equalized across the system

– Hottest power stage can operates cooler as a result.

– TI measurements show ~5 degC temperature reduction for hottest power stage

• Per-phase OCL does not get scaled by Thermal balance

– Phases with better thermal grounding (e.g. which are given more current than avg.) do not need

over-sized inductors or higher OCL than other phases.

– All phases protected from inductor saturation, all the time.

– No impact to transient response, unless phases trigger OCL. In designs with low margin, phases

given more current, can trigger OCL more quickly, leading to slightly more undershoot.

• DC Loadline is based on ISUM current no impact to DCLL

• AC Ripple Cancellation is still maintained Un-noticeable output ripple change
