is a CMOS-based PWM step-down DC-DC Controller. The device offers the following advantages: lower supply current and wider operating input-voltage range. The A7210 consists of an oscillator, a PWM control circuit, a reference voltage unit, an error amplifier, a soft-start circuit, a protection circuit, a PWM/PFM alternative circuit, a Chip Enable circuit, and under voltage lockout circuit. A low ripple, high efficiency step-down DC-DC converter can be easily composed of this IC. Output Voltage can be adjusted with external resistors. The A7210 uses voltage type PWM/PFM mixed operation mode. When the load current is small,
