LTC3839EUH: Two-phase, single-output buck DC/DC controller, QFN-32

The LTC3839EUH is a two-phase, single-output, multi-phase (PolyPhase®) synchronous buck switch mode regulator controller designed to drive all N-channel power MOSFETs. The controlled on-time, valley current mode control architecture enables fast transient response and constant frequency switching action in steady-state operation, unaffected by VIN, VOUT, and load current. Its load release transient detection feature significantly suppresses overshoot under low output voltage conditions.

LTC3839EUH Product Features:

Wide VIN range: 4.5V to 38V, VOUT: 0.6V to 5.5V

Output voltage accuracy of ±0.67% over the entire temperature range, differential output voltage detection, allowing up to ±500mV line loss at remote ground

Controlled on-time, valley current mode control

Fast load transient response

Transient detection function (DTR) suppresses VOUT overshoot

Frequency programmable range from 200kHz to 2MHz, synchronisable to an external clock

tON(MIN) = 30ns, tOFF(MIN) = 90ns

Up to 12-phase operation

RSENSE or inductor DCR current sensing  

Overvoltage protection and current limit foldback  

Power good output voltage monitor  

Output voltage tracking and adjustable soft start  

Thermally enhanced 32-pin (5mm x 5mm) QFN package  

LTC3839EUH Applications:  

Distributed power systems  

Point-of-load converters  

Computing systems  

Data communication systems

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
