The APE2902 architecture is built around a VFM CONTROL logic core, switching
frequency is set through a built in oscillator. TON time is fixed (Typ. 5uS) while TOFF time is
determined by the error amplifier output, a logic signal coming from the comparison made
by the Error Amplifier Stage between the signal coming from the output voltage divider
network and the internal Band-Gap voltage reference (Vref). TOFF reaches a minimum
(Typ. 1.7us) when heavy load conditions are met (Clock frequency 150KHz). An over
current conditions, through the internal power switch, causes a voltage drop VSW=RDS(ON)
x ISW and the VSW limiter block forces the internal switch to be off, so narrowing TON time
and limiting internal power dissipation. In this case the switching frequency may be higher
than the 150KHz set by the internal clock generator.
VFM control ensures very low quiescent current and high conversion efficiency even
with very light loads. Since the Output Voltage pin is also used as the device Supply
Voltage, the versions with higher output voltage present an higher internal supply voltage
that results in lower power switch RDS(ON), slightly greater output power and higher
efficiency. Moreover, bootstrapping allows the input voltage to sag to 0.6V (at IOUT=1mA)
once the system is started. If the input voltage exceeds the output voltage, the output will
follow the input, however, the input or output voltage must not be forced above 5.5V.
