Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Hello SSC,
Lower values are ok as well. In the datasheet we just try to select a good tradeoff between power loss and noise immunity. Please have a look to this app note for the details on how to select a good resistive feedback divider: Design considerations…
Part Number: PMP9759 Hi
I am looking for bidirectional TEC control so I am able to cool or heat. Do you know if this development board can do this.
If it does can you explain how.
Thank you
Part Number: PMP9759 Other Parts Discussed in Thread: MSP430F5529 I would like to know what is the temperature accuracy you can get with this microcontroller based TEC temperature controller? And also can you please tell me which microcontroller have you…
Part Number: PMP9759 Other Parts Discussed in Thread: LM5175 Hi TI team!
Part number: PMP9759 I would like to know, is it possible to modify this project to get up to 5-6Amp output power to drive the Peltier TEC-12706 for example.
Or another simple…
Part Number: TPS63020 Other Parts Discussed in Thread: PMP9759 Hello,
I am using the Pspice model for the TPS63020 and configuring it to drive a TEC (simply modeled as a 2 Ohm resistor). I am making connections as shown in the app note, PMP9759. The spice…
Michael, the TMS320F2812 device is still active on ti.com. This evaluation module, while I never worked with it, is from 2002 and is most certainly no longer sold. When products get removed from the TI store most of the associated webpages are removed…
Part Number: TPS63020 Other Parts Discussed in Thread: PMP9759 , We are building a Peltier driver based on http://www.ti.com/tool/PMP9759 .
Our test circuit is not stable. We notice that the stability improves if low-impedance Peltiers are used (thus higher…
Hi Andrew,
TPS62135/6 can output up to 4A to up to 12Vout.
If you need higher current, a device like TPS54824 might work.
Here's a simple reference design that shows how to adjust the output voltage of any DC/DC to drive a TEC: http://www.ti.com…
Hello Tsukui-san,
PWM dimming should not be done on the EN pin because there is a softstart triggered when EN is going high. This might cause visible effects on the LED.
This would be done on the FB node like in the TEC driver design PMP9759 (but this…
Hello Paul, This ripple seems to be too high, more than 2 Vpp, and looks more like some kind of oscillations due to instability of the circuit, and not due to switching/mode of the regulator (or L/Cout values). At loads below 600 mA, TPS63070 works in…
