1.2A Synchronous DC-DC Step Down Regulator
FEATURES
DESCRIPTION
Wide output voltage range : 1.15V to 2.80V
Input voltage range : 2.5V to 5.5V
Up to 1200mA Output Current
Load transient response is fast
Output current limit control of 1.8A to prevent
Excessive current flows
High efficiency over a wide load current area by
DCM (discontinuous conductive mode) operation
at light loads, CCM (continuous conductive mode)
operation in heavy loads those two modes can be
automatically switched
Switching frequency of 2.6MHz during CCM.
100% duty operation when input voltage goes
down to output voltage.
9 pin Wafer level chip size package (WLCSP Type)
Size : 1.46 1.46 mm ( 0.5 mm pitch)
AN30180A 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.
APPLICATIONS
High Current Distributed Power Systems such as
power amplifier in cellular phone etc.

Notes) Do not apply external currents and voltages to any pin not specifically mentioned.
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 guaranteeable 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.
*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 = 25C.
*3:VIN is voltage for AVIN, PVIN. AVIN = PVIN,(VIN + 0.3) V must not be exceeded 6 V.
