Preliminary specification
TEA1210TS
External synchronization
If an external high-frequency clock is applied to the
synchronization clock input, the switching frequency in
PWM mode will be exactly that frequency divided by 22.
In PFM mode, the switching frequency is always lower.
The quiescent current of the device increases when an
external clock is applied. In case no external
synchronization is necessary, the synchronization clock
input must be connected to ground level.
Behaviour at input voltage exceeding the specified
range
In general, an input voltage exceeding the specified range
is not recommended since instability may occur. There are
two exceptions:
• Upconversion: at an input voltage higher than the target
output voltage, but up to 6 V, the converter will stop
switching. As long as the device is in the PWM mode,
the internal P-type power MOSFET will be conducting
and the output voltage will equal VI minus some resistive
voltage drop. In case the converter is in the PFM mode
at high input voltage, the output voltage will equal
VI minus the voltage drop over the external diode.
The current limiting function is not active.
• Downconversion: when the input voltage is lower than
the target output voltage, but higher than 2.9 V, the
P-type power MOSFET will stay conducting resulting in
an output voltage being equal to the input voltage minus
some resistive voltage drop. The current limiting
function remains active.
