Part Number: TPS62243-Q1 Hi,
This is the circuit we are using to get 1.8V from TPS62243QDDCRQ1. But instead of fixed 1.8V we are getting 2.3V. We are using 3V coin cell battery. Why is it so and what are the steps to rectify it.?
Thanks,
Nivethitha…
Part Number: TPS62243-Q1 Other Parts Discussed in Thread: TPS62240 Hi,
I downloaded spice model for TPS62243-Q1(Buck converter) and tried simulation in both Ltspice and pSpice. The IC shown in datasheet has only 5 pins, but the Spice model has an extra…
Part Number: TPS62243-Q1 Other Parts Discussed in Thread: CC2640 , , TPS62740 , TPS62243 Hello,
We are developing the IoT product based on CC2640 (CC2640F128RGZ).
Also, we want to use the Step-down converter that is the "TPS62243-Q1".
I know that…

The TPS62242 / TPS62243 seem to be amongst TI's most efficient sub 30mA 3V3 to 1V8 and 1V2 DC-DC converters.
1. Is feed-forward compensation (capacitor…
Part Number: TPS61021A Other Parts Discussed in Thread: TPS62243 I have a design which uses the TPS61021A to generate 3.6V from a AAA alkaline battery. The enable pin is pulled to ground through a 100k resistor and the design holds the regulator in shutdown…
Hello Luna,
What device are you using? In general, the footprint and solder mask information is in the CAD file section for the device.
For example , the TPS62243 is a DDC-5 package: http://www.ti.com/product/TPS62243-Q1 .

Nick, great feedback! I feel really confident in this design now. I just want to make sure this is consistent with your reply before I resolve the issue. I'm generating +1.8v from the TPS62243 which feeds into an LP5907 for +1.5v and a TPS723 with an…
Hi Yuvaraju,
I looks like 4.7uH inductor is only an option for variable output voltage. In any case, you might want to consider TPS62243 which uses 2.2uH inductor with fixed switching frequency of 2.25MHz. See the link below for the datasheet.
