AX3001 Application Note

GENERAL DESCRIPTION
    The AX3001 series are monolithic IC designed for a step-down DC/DC converter,
and own the ability of driving a 2A load without additional transistor. It saves board space. The external shutdown function can be controlled by logic level and then come into standby mode. The internal compensation makes feedback control having good line and load regulation without external design. Regarding protected function,thermal shutdown is to prevent over temperature operating from damage, and current limit is against over current operating of the output switch. If current limit function occurs and VFB is down below 0.5V, the switching frequency will be reduced. The
    AX3001 series operates at a switching frequency of 150KHz thus allow smaller sized filter components than what would be needed with lower frequency switching
regulators. The output version included fixed 3.3V, 5V, 12V, and an adjustable type. The chips are available in a standard 8-lead SOP package.

FEATURES
- Output voltage: 3.3V, 5V, 12V and adjustable output version.
- Adjustable version output voltage range, 1.23V to 19.5V.
- 150KHz fixed switching frequency.
- Voltage mode non-synchronous PWM control.
- Thermal-shutdown and current-limit protection.
- ON/OFF shutdown control input.
- Short Circuit Protect (SCP).
- Operating voltage can be up to 22V.
- Output load current: 2A.
- SOP-8L Pb-Free packages.
- Low power standby mode.
- Built-in switching transistor on chip.
