EV3416-J-00A 1.1A Switching Current Low Iq, step-up converter Output Disconnect Evaluation Board DESCRIPTION FEATURES EV3416-J-00A evaluation board is designed to demonstrate the capability of MP3416. The MP3416 is a 1.1A switching current, low quiescent current, step-up converter with output disconnect. The MP3416 works in peak current control mode, providing good transient response. The integrated P-channel synchronous rectifier improves efficiency and eliminates the need for an external schottky diode. The device enters pulse skip mode to save power loss in light load condition. When the part shuts down, the output is disconnected from input, allowing the part to draw less than 0.65μA in shutdown mode. The MP3416 is available in a small 8-pin TSOT23 package.

All Rights Reserved. 6 EV3416-J-00A–1.1A SWITCHING CURRENT LOW QUIESCENT STEP-UP CONVERTER EV BOARD Quick Start Guide The output voltage of this board is set to 3.3V. The board layout accommodates most commonly used components. 1. Preset Power Supply to 1.25V ≤ VIN ≤ 5.5 V. 2. Turn Power Supply off. 3. Connect Power Supply terminals to: a. Positive (+): VIN b. Negative (–): GND 4. Connect Load to: a. Positive (+): VOUT b. Negative (–): GND 5. Turn Power Supply on after making connections. 6. The MP3416 is enabled on the evaluation board once VIN is applied. 7. The output voltage VOUT can be changed by varying R2. Calculate the new value using the formula: VOUT VFB (1 R1 ) R2 Where VFB = 0.504V and R1=1MΩ. 8. To use the enable function, apply a digital input to the EN pin. Drive EN higher than 0.7V to turn on EV3416-J-00A or less than 0.2V to turn it off. NOTICE: The information in this document is subject to change without notice.
