Operating Temperature: Industrial grade (-40 to +85 ) (output power 10W or less). Full load temperature rise 40. Load regulation ± 0.5 percent. Voltage regulation ± 2.5 percent. Dynamic response speed 5 percent 200uS. Specification Input Voltage: 3-40V. Output Voltage: 1.5-35V(adjustable). Output Current: Rated current is 2A,maximum 3A (additional heatsink is required). Dimension: 45 x 20 x 14mm (L x W x H). Review: Great ❤️ - Works great ❤️ Review: Overall quality is good. - I bought 2 of the step down converters. One of them has its inductor loose. I had to use hot glue to fix the wobbling because I was afraid that it would break. The converter does not heat up too much so that's good. I have not opened the other one yet but after noticing the wiggle in the first one I checked the other one in the package. The second one was not damaged so that's ok. At last one suggestion that I would give is to have a power indicator light. ## Features - Input: DC 3V to 40V (input voltage must be higher than the output voltage to 1.5v above can not boost) - Output: DC 1.5V to 35V voltage continuously adjustable, high-efficiency maximum output current of 3A - Features: All Sanyo solid capacitors, the 36u thickening circuit boards, high-Q inductance with output value of high-power LED indicator - Dimensions: 45 (L) x 20 (W) x 14 (H) mm (with potentiometer) - weight: 20 gms ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B009P04YTO | | Are batteries included? | No | | Best Sellers Rank | #3,882 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #1 in IO Modules | | Brand | Generic | | Colour | Multicolour | | Customer Reviews | 3.8 3.8 out of 5 stars (1,254) | | Date First Available | 20 March 2014 | | Item Dimensions LxWxH | 150 x 150 x 100 Centimeters | | Item Height | 100 Centimeters | | Item Weight | 20 g | | Item Width | 150 Centimeters | | Item model number | LM2596 | | Manufacturer | Generic | | Model number | LM2596 | | Net Quantity | 1 Count | | Packer | Bombay Electronics, 13B Shamrao Vithal Marg, Off Lamington Road.

Just worried about the current part.** A: No. LM2596 is limited up to 3A Output Load Current. The Input Voltage Range is up to 40V, though. **Q: Can i use it as car charger for tablets?** A: Nope, It will fry before you blink **Q: My input is pmax 1.3 w, voltage at pmax (vmp): 7.5 v. would like to convert 5 v (for mobile usb charging). does it fulfil this?** A: Yes ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great ❤️ *by A***Y on 28 February 2026* Works great ❤️ ### ⭐⭐⭐⭐ Overall quality is good. *by A***S on 19 April 2017* I bought 2 of the step down converters.

Not for stepping up. *by P***D on 17 July 2024* This converter board is working well for stepping down the voltage, however it is not working for stepping up as one might look at its functioning. This has LED to show up that it’s working well. Once set up then it is giving constant output to the set value. Set value don’t change by on/off of this module. I have tested it on battery. On 3.7 volt Li-ion battery it seems to refuse to work very hard. However on 12v SLA battery it is working brilliantly and came down to the most common voltage of 5.0v exactly. Now whenever I’m switching it on it’s giving up fixed output of 5.0 volts. I believe this module has great purpose and solutions to everyday life. For example this can avoid the need of a car charger or another costly charger if wired for charging phones or tablets. Working well.
