EP1551 Evaluation Board Manual
Description
This manual aims to illustrate how to use the EP1551 Evaluation Board (“EP1551 EVB”).
The
EP1551 EVB
is a fully assembled and tested circuit board that accepts 1.5V to 3.6V input
voltages and provides all the output voltages required for a typical digital still camera. The outputs
consist of a main step-up output (3.35V), a step-down output (1.5V), a general-purpose 5V output,
two outputs for charge-coupled device (CCD) and LCD bias.
This manual includes Quick Start for using the EP1551 EVB, Demonstration Circuit, PCB Layout and Bill
of Material for the EP1551 EVB.
Quick Start
The EP1551 EVB is easy to set up to evaluate the performance of the EP1551, 1MHz, Five-channel Power
Supply. For proper measurement equipment setup, please follow the explanation below:
Follow the steps below to verify operation of the
EP1551 EVB
.
Do not turn on the power supply until all connections are completed:
1) Preset the power supply to between 1.5V and 3.6V.
2) Turn off the power supply.
3) Connect the power-supply positive lead to IN.
4) Connect the power-supply ground lead to GND.
5) Connect loads from outputs OUTSD (1.5V), OUT1 (5V), OUT3A (+15V), and OUT3B (-7.5V) to
GND. See as below Table for
Output Voltages and Maximum Currents.
6) To enable the main step-up output, verify that JP1 has short to MAIN pin.
7) Verify that JP2–JP8 have pins 1 and 2 shorted.
8) Turn on the power supply.
9) Use a voltmeter to verify the OUTSU voltage (3.35V).
10) Connect a load, if desired, from OUTSU (3.35V) to GND. See Table 1 for maximum load currents.
11) To verify other outputs, move JP2–JP5 to short to MAIN pin. Use a voltmeter to verify output
voltages.
P.S. We already have surface-mount LEDs in DS1–DS4, connecting the LED array from anode to
LEDOUT+ to cathode LEDOUT-.
