MAX20002ATPA/V+T Analog Devices

EVALUATION KIT AVAILABLE MAX20002/MAX20003 36V, 220kHz to 2.2MHz, 2A/3A Fully Integrated Step-Down Converters with 15A Operating Current General Description Benefits and Features The MAX20002/MAX20003 are small, synchronous Synchronous DC-DC Converter with Integrated FETs buck converters with integrated high-side and low-side Improves Efficiency and Eases Design MOSFETs. Each device is designed to deliver up to 2A/3A MAX20002 = 2A with input voltages from 3.5V to 36V, while using only MAX20003 = 3A 15A quiescent current at no load. Voltage quality can be 15A Quiescent Current When in Standby Mode monitored by observing the PGOOD signal. The devices Small Solution Size Saves Space can operate in dropout by running at 98% duty cycle, 220kHz to 2.2MHz Adjustable Frequency making them ideal for automotive applications. Programmable 1V to 10V Output for the Buck or Fixed 5V/3.3V Options Available The devices offer fixed output voltages of 5V/3.3V, along with the ability to program the output voltage between 1V Fixed 8ms Internal Soft-Start Fixed Output Voltage with 2% Output Accuracy to 10V. Frequency can be programmed using a resistor (5V/3.3V) or Externally Resistor Adjustable (1V to to ground on the FOSC pin from 220kHz to 2.2MHz. The 10V) with 1% FB Accuracy devices offer a forced fixed-frequency mode and skip mode with ultra-low quiescent current of 15A. They have PGOOD Output and High-Voltage EN Input Simplify a pin that can be programmed to turn on/off the spread Power Sequencing spectrum, further helping systems designers with better Protection Features and Operating Range Ideal for EMC management. Automotive Applications The MAX20002/MAX20003 are available in a small 5mm x Operating V Range of 3.5V to 36V IN 5mm 20-pin TQFN package with exposed pad and use very 42V Load-Dump Protection few external components. 99% Duty-Cycle Operation with Low Dropout Spread-Spectrum Control with a Pin Reduces EMI Applications -40C to +125C Automotive Temperature Range Point-of-Load Applications in Automotive AEC-Q100 Qualified Distributed DC Power Systems Navigation and Radio Head Units Ordering Information appears at end of data sheet. 19-7311 Rev 2 2/15MAX20002/MAX20003 36V, 220kHz to 2.2MHz, 2A/3A Fully Integrated Step-Down Converters with 15A Operating Current Typical Application Circuit/Block Diagram V = 3.3V/5V OUT AT 3A, 2.2MHz 2.2H 0.1F 2 x 22F FOSC BST 12k OUT PGND MAX20002 MAX20003 FB PGND COMP SPS 20.0k BIAS PGOOD 2.2F 1,000pF VBAT 2.2F 4.7F Maxim Integrated 2 www.maximintegrated.com AGND FSYNC EP N.C.
