Hi,
Application Report SLUA979A describes a circuit using the TPS54201 to drive a Peltier Module (TEC) in constant current mode as opposed to PWM mode. However, the circuit using the TPS54201 is unidirectional and can therefore drive the TEC to either heat or cool but not both. Would it be possible to insert an H-Bridge into this circuit as shown in the schematic below to achieve bidirectional control of the TEC for both heating and cooling?
Regards,
James
