ADP1614

650kHz/1.3 MHz, 4 A, Step-Up,PWM, DC-to-DC Switching Converter
Manufactured by:

Product Details

The ADP1614 is a step-up, dc-to-dc switching converter with an integrated power switch capable of providing an output voltage as high as 20V. The ADP1614 is available with a pin-adjustable current limit that is set via an external resistor with the boost switching frequency fixed to either 650kHz or 1.3MHz. Alternatively, the ADP1614 is also available with fixed 3A current limit and a pin-selectable frequency. With a package height of 0.8mm, the ADP1614 is optimal for space constrained applications, such as portable devices or thin film transistor (TFT) liquid crystal displays (LCDs).

The ADP1614 operates in current-mode pulse-width modulation (PWM) with up to 94% efficiency. Adjustable soft start prevents inrush currents when the part is enabled. The PWM current-mode architecture allows excellent transient response, easy noise filtering, and the use of small, cost-saving external inductors and capacitors.Other key features include undervoltage lockout (UVLO), thermal shutdown (TSD), and logic controlled enable.

The ADP1614 is available in Pb-free, 10-lead lead frame chip scale package (LFCSP).

Applications
  • TFT LCD bias supplies
  • Portable applications
  • Industrial/instrumentation equipment

This page contains the ordering guide information for evaluating ADP1614.

Product Details

In order to get the correct unpopulated evaluation board with an appropriate Bill of Materials and Schematic, you need to use the button for "Request Evaluation Board" from within the design tool. Make sure the design tool is in a state that matches your desired power requirements.

This will create a template email that will request from us the proper blank evaluation board for that ADI part and your application's power parameters.


Note: Some parts have multiple blank boards for high/low current or for different topologies (Boost, SEPIC, SEPIC-Cuk), while other blank boards support multiple ADI parts. This is why it is important to run the design tool with your parameters before making your email request from the tool.

If the output diode (switch) would be integrated, too...

Great chip, handles well under some rough conditions. I recommend it, and it also works good under SEPIC CUK topology.

A lot of power from tiny IC
Tried this Step-Up for an application requiring at least 2Amp on 5V side, asked Analog for their evaluation boards, very simple to test the ADP1614 in both PWM frequency available. What to say? You can have up to 4Amps out from this little device!
