Part Number: LMR36500 Other Parts Discussed in Thread: LM5019 Hello TI members,
Question1:
How much current (sink/source) is required on pin 3 (EN/UVLO) of LMR36500 to enable the device? I plan to use an optocoupler for controlling the EN/UVLO pin and…
Part Number: LMR36500 Hi,
Need some FACE support for selecting the right device (IBB controller with integrated power stage):
Input voltage range: +4.5V...+26V
Output voltage range: -1.5V... -6V
Output current: 0 to -50mA Small overall size and cost.
…
Hi Greg,
The LMR36500 would probably be the better choice.
For a typical application, I would suggest a 2x 2.2uF capacitor, 100V rating (to account for derating), with a 100nF capacitor at the input. An output capacitor around 4.7uF would probably also…
Hi Brandon,
Thanks for confirming. MCU/MPU will be on separate power supply, I will use isolators in between PSE and MCU/MPU. Also to down convert from 48V to 3.3V, I plan to use LMR36500 which as output current of upto 50mA, is this fine or an LDO is…
Hi Chris,
Thank you for this information! I am only able to comment on the DC/DC converter solutions we have available. From my understanding, you have two parts:
24 VIN, 5 VOUT, 10 mA max
24 VIN, 3.3 VOUT, 200 mA max
These are the devices I can recommend…
Hi Fabio,
I think for light-load efficiencies, you may want to look for the LMR36500, LMR36501, or LMR36502. It can run into light loads up to 200mA, which may help with your efficiency requirements.
Usually for comparing efficiencies, I suggest checking…
