1 / 17 page  AN30180A 1 Ver. AEB 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) High Current Distributed Power Systems such as power amplifier in cellular phone etc. SIMPLIFIED APPLICATION APPLICATIONS FEATURES DESCRIPTION VIN = 2.5V to 5.5V 1.2A Synchronous DC-DC Step Down Regulator 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.

The operation of mass production set is not guaranteed. You should perform enough evaluation and verification on the design of mass production set. You are fully responsible for the incorporation of the above application circuit and information in the design of your equipment. 4.7 μF x 2 1.0 μH 4.7 μF EFFICIENCY CURVE Publication date: October 2012 |
