DETAIL DESCRIPTION and GUIDELINES (continued)
Reference Circuit
A high precision bandgap is used giving a low TC and good supply rejection. The output is attenuated to give a reference
voltage of 0.600V making it suitable for very low output voltage applications.
COMPENSATION
The converter is of the current mode topology considered simplifying the selection of compensation components. For most
voltages this simple formula is a good starting point
Ccomp = 15e-9/Vout for L = 10e-6 and Cout = 44e-6
Ccomp is proportional to the output inductors and output capacitor
Rcomp = 18e3/Vout
Output capacitor Cout, is a function of the maximum current and ripple required.
Multiple capacitors may be required to give the optimum ripple and transient response.
The stability is not that critical for varying Cout, however to prevent OCP during fast load transients Ccomp, has to be increased
in proportion to Cout.
The current gain of the output stage is approximately 6A/volt
The running transconductance output current is
Sourcing current 95 μA
Sinking current 85 μA
This equates to about 600e-6 mohs
For best transient response each application is unique and these components should only be used as a starting point.
