1.2 A Synchronous DC-DC Step Down Regulator
(VIN = 2.5 V to 5.5 V, VOUT = 1.20 V to 3.30 V)
FEATURES
Wide output voltage range : 1.20 V to 3.30 V
Input voltage range : 2.5 V to 5.5 V
Maximum Output Current : 1.2 A
Load transient response is fast
Output current limit control of 1.8 A to prevent
Excessive current flows

at light loads, CCM (continuous conductive mode)
operation in heavy loads those two modes can be
automatically switched
Switching frequency of 2.6 MHz during CCM.
100 % duty operation when input voltage goes
down to output voltage.
Built-in Under Voltage Lockout (UVLO),
Thermal Shut Down (TSD),
Over Current Protection (OCP),
Short Circuit Protection (SCP)
9 pin Wafer level chip size package (WLCSP)
Size : 1.46mm 1.46 mm (0.5 mm pitch)
DESCRIPTION
AN30180AA is a synchronous DC-DC Step Down
Regulator and employs the hysteretic control system.
By this system, when load current charges suddenly,
it responds at high speed and minimizes the changes
of output voltage.
Since it is possible to use capacitors with small
capacitance and it is unnecessary to add external
parts for system phase compensation, this IC realizes
downsizing of set and reducing in the number of
external parts.
Output voltage is adjustable by control pin.
Maximum current is 1.2 A.
APPLICATIONS
High Current Distributed Power Systems such as
power amplifier in cellular phone, camera etc.

Note : The application circuit is an example. The operation of
the mass production set is not guaranteed. Sufficient
evaluation and verification is required in the design of
the mass production set. The Customer is fully
responsible for the incorporation of the above
illustrated application circuit in the design of the
equipment.

Notes : This product may sustain permanent damage if subjected to conditions higher than the above stated absolute
maximum rating. This rating is the maximum rating and device operating at this range is not guaranteed as it
is higher than our stated recommended operating range.
When subjected under the absolute maximum rating for a long time, the reliability of the product may be affected.
VIN is voltage for AVIN, PVIN. VIN = AVIN = PVIN.
Do not apply external currents and voltages to any pin not specifically mentioned.
*1 : The values under the condition not exceeding the above absolute maximum ratings and
the power dissipation.
*2 : Except for the power dissipation, operating ambient temperature, and storage temperature,
all ratings are for Ta = 25 C.
*3 : (VIN + 0.3) V must not exceed 6 V.
