EV3209DJ-00A 1.3MHz 350mA Boost Converter Evaluation Board The Future of Analog IC Technology GENERAL DESCRIPTION FEATURES The EV3209DJ-00A is the evaluation board for the MP3209. The MP3209 is a current mode step up converter intended for small, low power applications. The MP3209 switches at 1.3MHz and allows the use of tiny, low cost capacitors and inductors to achieve a solution less than 1mm in height. Internal soft start results in small inrush current and extends battery life. • • • • • • • The MP3209 includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload. The MP3209 is available in small 5-pin TSOT23 and 2mm x 2mm ultra-thin QFN 8-pin packages. • • • ELECTRICAL SPECIFICATION Parameter Input Voltage Output Voltage Symbol Value Units VIN VOUT 2.5 to 6 15 V V 2.5V to 6V Input Voltage Range On Board Power MOSFET Uses Tiny Capacitors and Inductors 1.3MHz Fixed Switching Frequency Internally Compensated Internal Soft-Start Operates with Input Voltage as Low as 2.5V and Output Voltage as High as 22V UVLO, Thermal Shutdown Internal Current Limit Available in TSOT23-5 and Ultra-Thin 2x2 QFN Packages APPLICATIONS • • • • Cell Phones External Modems Small LCD Displays OLED Drivers “MPS” and “The Future of Analog IC Technology” are Registered 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 ≤ 6V. 2. Turn Power Supply off. 3. Connect Power Supply terminals to: Positive (+): IN Negative (–): GND 4. Connect Load to: Positive (+): OUT Negative (–): GND 5. Turn Power Supply on after making connections. 6. The MP3209 is enabled on the evaluation board once VIN is applied. To disable the MP3209, short EN to GND. 7. The output voltage VOUT can be changed by varying R4. Calculate the new value using the fomula: ⎛ VFB R4 = ⎜⎜ ⎝ VO − VFB ⎞ ⎟ × R2 ⎟ ⎠ Where VFB = 1.25V and R2 = 499kΩ For example, for VOUT = 15V ⎛ 1.25 ⎞ R4 = ⎜ ⎟ × 499kΩ = 45.3kΩ ⎝ 15 − 1.25 ⎠ Therefore use a 45.3 kΩ standard 1% value.
