EV3429-L-00A 21A High Efficiency Fully-Integrated Synchronous Boost Converter EV Board The Future of Analog IC Technology DESCRIPTION FEATURES EV3429-L-00A Evaluation Board is designed to demonstrate the capability of MP3429. The MP3429 is a 600kHz fixed frequency, wide input range, highly integrated boost converter. It starts from an input voltage as low as 2.7V, and supports up to 30W load power from 1-cell battery. MP3429 adopts constant-off-time (COT) control topology providing fast transient response. One MODE pin supports mode selection of PSM, FCCM and USM in light load condition. And the integrated LS and HS MOSFET simplify the design and save BOM cost. F N The MP3429 is available in a 13-pin 3mmx4mm QFN package. O C Electrical Specification Parameter Input Voltage Output Voltage Symbol VIN VOUT S P Output Current Iout Note: Value 2.7-8.4 9 Units V V A 3.5(1) 1) When VIN=2.7V, IOUT=3.5A, the case temperature should be high, It is limited by PCB size.

The board layout accommodates most commonly used components. Following blew steps to quick start EV3429-L-00A. 1. Preset Power Supply to 2.7V ≤ VIN ≤ 8.4V. 2. Turn Power Supply off. T 3. Connect Power Supply terminals to: a. Positive (+): VIN N b. Negative (–): GND E 4. Connect Load to: a. Positive (+): VOUT D I b. Negative (–): GND A I 5. Turn Power Supply on after making connections. F N 6. The MP3429 is enabled on the evaluation board once VIN is applied. U B I R E T 7. The output voltage VOUT can be changed by varying R2. Calculate the new value using the formula: VOUT O C R1 VFB (1 ) R2 Where VFB = 1V and R1=750kΩ. 8. If USM and FCCM is needed, following below steps: T a. Turn Power Supply off. S I D b. Change J1 connection. Connect 1 to 2 for FCCM, connect 2 to 3 for PSM, and float 2 for USM. S P c. Turn the power on. IC will work with the mode which is set by step b.
