Preliminary Data Sheet
TDA21201
Designing a 12 V to sub-3.3 V converter using the TDA21201
General info
To design a multi-phase converter with a 12 V input simply use in each phase
just one TDA21201 instead of using a MOSFET driver, a high side MOSFET,
bootstrap components, and one or more low side MOSFETs. The entire
converter is completed by the input filter, the output filter and a multi-phase
PWM IC.
Input compatibility to standard PWM controllers / shut-down mode
The Integrated Switch TDA21201 has a high impedance input pin ‘IN’ to be
connected to PWM controller outputs ‘PWM1’, ‘PWM2’ etc. It sinks or sources
only a fraction of a mA from the controller’s output. The TDA21201 is
compatible to standard controller and driver signals in terms of the signal level
(5 V TTL) and in terms of the ‘Low’/’High’ relationship (’Low’ turns the low side
MOSFET on, ‘High` turns the High side MOSFET on).
The TDA21201 can be shut down (the high side MOSFET and the low side
MOSFET is turned off) by applying an input signal V
IN
= 1.2 ... 1.6 V for more
than 1.5 μs typical. This way the TDA21201 reduces the power dissipation by
saving the gate charges of both the high side and the low side MOSFET
during no load conditions. The shutdown state is terminated when V
IN
moves
into the ‘Low’ or ‘High’ threshold.
