## Description

Electrical Parameters:Input: DC 3.2V to 35V (input voltage must be more than the output voltage can not be higher than boost 1.25v.)Output: 1.25V to 30V DC voltage is continuously adjustable, high efficiency and maximum output current of 3A.Features: All solid capacitors using SANYO, 36u thick circuit boards, high-Q inductors with high power output LED indicatorSize: 45 21 13mm / 1.69 0.83 0.51inch (including potentiometers)minimum with locating hole with LED indicator DC-DCInstructions:Access to power (3-35V), adjust the blue potentiometer knob (clockwise rotation generally boost, buck counterclockwise rotation) and with a multimeter to monitor the output voltage reaches the required voltage.Wiring:1. welding, welded directly to the power line input (output) port;2. solder pins, or pins can be inserted through the lead insertion use in tunnel plate; soldered directly to the PCB after another or add pins.Note: The input and output can not be reversed, reverse might burn chips;This is a step-down module, the input voltage is higher than the required output voltage;Output 2A or less long period of time without additional heat sink output current is greater than 2.5A (or output power greater than 10W) to work long hours please add heat sink.Package Included: 10pcs X LM2596S Module

Review: Works great! I use them to reduce 15V voltage to power LED post lights, which require 1.2V. The output resistor needs to be adjusted to reduce voltage because by default the output voltage it too high.
Review: Llego muy rápido y funcionan a la perfección, muy buena atención.

## Questions & Answers

**Q: Will v-out stay stable w/ a changing v-in? for instance 14v in and set for 3 v out but over time input (battery) drops to 11v.**
A: I haven't monitored the Output Voltage vs. Input Voltage change, but I have noticed that the output tends to drift down as the output current increases.  I haven't seen it drop below the 2.5% allowed in the spec, though, and I have drawn as much as 2.3 Amps.

**Q: Is there any delay when supplying voltage till output is sent?**
A: Output voltage begins to ramp up within a few micro seconds (usec) of applying input voltage but it takes a few hundred usec to reach full output voltage.  The time to achieve full output depends on both the input and output voltage.  I was curious so I measured a few cases.  The times to reach full output voltage with a 470 Ohm load were:
10.0V in, 5.0V out: 288 usec
20.0V in, 5.0V out: 304 usec
20.0V in, 15.0V out: 570 usec
30.0V in, 15.0V out: 572 usec
30.0V in, 25.0V out: 662 usec
Cheers

**Q: I don't understand the limitations. Can it be used to bring 5V down to 3V?**
A: It absolutely can. I have used these to convert my 12V supply into both 5V and 3.3V

**Q: At 12 volts input and (say) 5 volts output, what is the quiescent (no-load) current on the 12 volt side?  Thanks!**
A: On my regulators the no load input current for 12V in 5V out is 7.8 mA with the output indicator LED installed.  With the LED, the no-load current depends strongly on output voltage rising to 23 mA  at 11V output.  With the LED removed the no load input current at 12 V in 5 V out is 6.0 mA.  Without the LED is independent of output voltage.
