ADP1073AN-5 AD [Analog Devices], ADP1073AN-5 Datasheet - Page 3

• Manufacturer Part Number: ADP1073AN-5
• Description: Micropower DC.DC Converter Adjustable and Fixed 3.3 V, 5 V, 12 V
• Manufacturer: AD [Analog Devices]

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the ADP1073 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.

Function
For normal conditions this pin is con-
nected to V
limit is required, a resistor should be
connected between I
ing the switch current to 400 mA is
achieved by connecting a 220
Input Voltage.
Collector Node of Power Transistor.
For step-down configuration, connect to
V
to an inductor/diode.
Emitter Node of Power Transistor. For
step- down configuration, connect to
inductor/diode; for step-up configura-
tion, connect to ground. Do not allow
this pin to drop more than a diode drop
below ground.
Ground.
Auxiliary Gain (GB) Output. The open
collector can sink 100 A.
Gain Amplifier Input. The amplifier’s
positive input is connected to the SET
pin and its negative input is connected
to the 212 mV reference.
On the ADP1073 (adjustable) version
this pin is connected to the comparator
input. On the ADP1073-3.3, ADP1073-
5 and ADP1073-12, the pin goes di-
rectly to the internal application resistor
that sets output voltage.
