Adjustable Output DC-DC Power Supply with Ultra-Wide Input and 6A Output

$39.00$39.75

The pt1-OKLT6W12-5V5max is a robust and stable power supply providing four outputs, adjustable from 0.59V to 5.5V, at a maximum of 6A. The board is built around a Murata OKL-T/6-W12 DC-DC switching (buck) converter, not requiring a heat sink.

The input voltage can be anywhere between 4.5V and 14V, supplied through the screw connector or the barrel jack connector.

0.59-5.5V Adjustable Output DC-DC Power Supply, 4.5-14V Ultra-Wide Input, 6A Output

The pt1-OKLT6W12-5V5max is a robust and stable power supply providing four outputs, adjustable from 0.59V to 5.5V, at a maximum of 6A. The board is built around a Murata OKL-T/6-W12 DC-DC switching (buck) converter, not requiring a heat sink.

The input voltage can be anywhere between 4.5V and 14V, supplied through the screw connector or the barrel jack connector.

The module features an onboard fuse, protecting the circuit against input polarity reversal. The power output is also protected against short circuits and over temperature. Once the short circuit condition is removed, the converter will automatically restore operation.

The circuit has added some translator logic to provide a (positive) logic ENABLE signal (e.g., 3.3/5V). Other signals available are SEQUENCE/TRACKING, PGOOD, and SENSE.

Features

  • 4.5-14V ultra-wide input, power provided through screw or barrel jack connector
  • four outputs, adjustable from 0.59v to 5.5V, at a maximum of 6A in total
  • built around Murata OKL-T/6-W12 DC-DC switching (buck) converter
  • very high efficiency, not requiring any heat sinks
  • protected against input polarity reversal through an onboard fuse
  • protected against short circuits and over-temperature
  • automatic restart after a short circuit
  • (positive) logic ENABLE signal (e.g., 3.3/5V)
  • SEQUENCE/TRACKING input (to guide/sync the output voltage build-up) available
  • PGOOD (Power Good) signal available
  • SENSE input (incorporating voltage feedback from load location) available
  • all based on robust through-hole components (except for the OKL-T/6-W12 converter)
  • the board is standing on four brass standoffs, allowing you to place it on a working table or integrate it into a larger assembly
  • board size: 59.25×36.75mm; bolts: 53.25×30.75mm (M2.5)
  • high-quality PCBs designed in KiCad and produced by Aisler (Germany), PCBWay (China), and OSH Park (USA)
  • the board comes fully assembled and tested
  • power cables available

NOTE: The full output voltage range runs from about 0.59V to 5.5V;
if you need a more limited range (to protect the hardware you will be connecting to this module), select one of the other (more restricted) ranges.

NOTE: Make sure the output current per connector is 3A max.

NOTE: The module will only start when a high logic ENABLE signal is provided;
if you need a module that is always on, select the type without the ENABLE signal logic.

Usage

I’ve created this board as a low-voltage power supply for my LED applications (often based on the TI TLC5947 constant current LED driver) and to feed the filaments of the VFD display tubes I use in my projects.

Shipping Policy

Please check your SPAM folder to ensure you accept emails from OzRobotics.com to receive your tracking number and download product-related files.

WE SHIP WORLDWIDE: We primarily ship via FedEx, UPS, DHL, and USPS because they’re reliable, fast, and easily trackable. We usually ship within two to three business days after the full payment. Standard delivery generally occurs within 5 to 7 business days after the shipping date. However, the delivery may take about 7 to 10 business days, depending on the shipping destination, logistics, weather conditions, product weight, size, or shipping company distribution structures.

SHIPPING COSTS: For some industrial products, e.g., heavy wheels, CNC machines, etc., the shipping cost is calculated based on the product weight, not quantity. To benefit from lower shipping costs for orders with multiple items, please contact us at sales@ozrobotics.com. Our shipping rates are listed clearly on each product page under the SHIPPING tab. Additionally, to see the shipping cost for your country, add the item to the Shopping Cart; you will see the shipping cost based on your Country and Location.

CUSTOMS and TARIFFS: While not all products require a tariff, some products may require a minimal tariff if applicable in your country. The total amount for your order does not include a customs fee/tariff. A tariff belongs to the buyer when applicable. Why don't we add tariffs to the product's retail price? - If all countries deducted the same tariff amount, we would have added the tariff amount to the product price. However, we do not do that because each country charges a different amount, while some do not even charge. Therefore, we can't add any tariff to the product's retail pricing. Oz Robotics, manufacturing partners, or Suppliers are not responsible for tariffs. Please check the "Made In:" and "Brand:" labels on the product page to see the product's origin. The total amount for your order does not include any duties, import taxes, customs fees, and GST/VAT. The buyer must pay all import duties. If you choose not to pay the tariff and parcel returns, there will not be any refund. Please click here to see more on Tariffs.
