EV3213DH-00A 700KHz/1.3MHz Boost Converter with a 3.5A Switch Evaluation Board The Future of Analog IC Technology DESCRIPTION FEATURES The EV3213DH-00A is an evaluation board for the MP3213. It is configured to provide a regulated 12V output at up to 0.5A from a 5V input. The output is adjustable from VIN up to 22V by changing resistors on the evaluation board. For an even higher output voltage, the input voltage needs to be extended higher. • The high switching frequency (700KHz or 1.3MHz) of the MP3213 allows for smaller external components, producing a compact solution for a wide range of load currents. Two user-selectable frequency options offer flexibility for easy filtering and low noise. The PCB heatsink with the exposed pad improves thermal performance and efficiency at medium to heavy loads. • • • • • • • Pin Selectable 700KHz or 1.3MHz Fixed Switching Frequency Operates with Input Voltage as Low as 2.5V 12V at 500mA from 5V Input Fully Assembled and Tested APPLICATIONS LCD Displays Portable Applications Handheld Computers and PDAs Digital Still and Video Cameras “MPS” and “The Future of Analog IC Technology” are Trademarks of Monolithic Power Systems, Inc.

The board layout accommodates most commonly used inductors and output capacitors. 1. Preset Power Supply to 2.5V ≤ VIN ≤ 10V. 2. Turn Power Supply off. 3. Place jumper J1 at the H position for 1.3MHz operation, or at the L position for 700KHz operation (the inductor may need to be adjusted accordingly). 4. Connect the power supply terminals to: Positive (+): VIN Negative (–): GND 5. Connect the load to: Positive (+): VOUT Negative (–): GND 6. Turn on the power supply after making connections. 7. The MP3213 is enabled automatically on the evaluation board once VIN is applied. To disable the MP3213, pull EN low. 8. The output voltage VOUT can be changed by varying R1. Calculate the new value using the formula: ⎛V ⎞ R1 = ⎜⎜ OUT − 1⎟⎟R2 ⎝ VFB ⎠ Where VFB = 1.25V and R2 = 10kΩ For example, for VOUT = 15V ⎞ ⎛ 15 V R1 = ⎜ − 1⎟ × 10kΩ = 110kΩ 1 . 25 V ⎝ ⎠ Therefore use a 110kΩ standard 1% value.
