Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The MAX20056BAUGB/V+ is a 6-channel LED driver with an integrated DC-DC switched boost/SEPIC controller and six 120mA sink current sources. The current-mode switching DC-DC controller provides the voltage required for the HB LED string.

The internal current-mode switched DC-DC controller supports boost, SEPIC or coupled inductor step-up/down circuits and operates over a programmable frequency range of 400kHz to 2.2MHz. Current-mode control provides fast response and simplifies loop compensation. Adaptive output voltage regulation method minimises power consumption in the LED current drive path.

External resistors allow individual channel currents to be set to the same value in the 20mA to 120mA range. The device features logic-controlled pulse width modulation (PWM) dimming with minimum pulse widths down to 500ns, with the option of phase-shifted LED or standard dimming control. When phase shifting is enabled, each string is switched on at a different time, effectively reducing input and output ripple and audible noise; when phase shifting is disabled, each current driver is switched on simultaneously, allowing parallel current drives to be achieved at currents higher than 120mA per string.

Features

High reliability, able to withstand EMC and automotive battery transients

Wide input voltage operating range of 4.5V to 42V to power HB LEDs, supporting medium/large LCD screens in automotive and display backlighting applications

Withstands up to 52V for automotive throw load applications

Integrated spread spectrum function

Spread Spectrum mode effectively reduces the switching frequency itself and its harmonic emissions

EMI suppression features include spread spectrum modulation (±6% of the switching frequency, set by the resistor connected between RT and SGND)

Phase shift dimming of LED strings

Reduced input and output ripple/audible noise

Wide contrast range to support high quality TFT and heads-up displays

10,000:1 @ 200Hz PWM dimming ratio

High reliability in terms of temperature and fault conditions

LED open/short detection

Overheat protection

Low shutdown current (< 15μA) via enable pin

Thermally enhanced 24-pin TSSOP package

-40°C to +125°C operating temperature range, AEC-Q100 compliant

Applications

• 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.
