AL2010
Current-Mode PWM Step-Down DC-DC Convertor
GENERAL DISCRIPTION
AL2010 is the Current-Mode Synchronous Step-Down DC-DC Convertor which offers excellent transient
response. Output voltage is selectable between 0.8V and 5.0V by the external resister. Input voltage range is
between 3.0V and 5.5V, and it is the most suitable to generate 1.0V, 1.2V, and 1.8V. Power MOSFETs are built
in AL2010, which is maximum current is 2.5A. The switching frequency is selectable between 300 kHz and 4
MHz by the external resister. For the protections, AL2010 has Over-Current protection, Low-Input Voltage
protection, and Power-Good function.
