In the event that either a thermal, short-circuit, or UVLO fault is de- tected, the SP6132H is forced into an idle state where the output drivers are held off for a finite ...

Error Amplifier and Voltage Loop As stated before, the heart of the SP6132H voltage error loop is a high performance, wide bandwidth transconductance amplifier. Be- cause of the amplifier’s current limited (+150µA) transconductance, there are many ways to com- pensate ...

Inductor Selection There are many factors to consider in selecting the inductor including cost, efficiency, size and EMI typical SP6132H circuit, the inductor is chosen primarily for value, saturation current and DC resistance. Increasing the inductor value will ...

Output Capacitor Selection The required ESR (Equivalent Series Resis- tance) and capacitance drive the selection of the type and quantity of the output capacitors. The ESR must be small enough that both the resis- tive voltage deviation due to a ...

The capacitor type suitable for the output capac- itors can also be used for the input capacitors. However, exercise extra caution when tantalum capacitors are considered. Tantalum capacitors are known for catastrophic failure when exposed to surge current, and input ...

The goal of loop compensation is to manipulate loop frequency response such that its gain crosses over 0db at a slope of -20db/dec. The first step of compensation design is to pick the loop crossover frequency. High crossover frequency is ...
