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.

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.
