Overview
AX3007C 52KHz, 2A PWM Buck DC/DC Converter  GENERAL DESCRIPTION The AX3007C 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.
4V, the switching frequency will be reduced.
The AX3007C series operates at a switching frequency of 52KHz thus allow smaller sized filter components than what would be needed with lower frequency switching regulators.
The output version is an adjustable type.
The chips are available in standard SOP8, SOP-8L-EP, TO252-5L and TO263-5L packages.
 FEATURES Output voltage: adjustable and fixed output versions.
Adjustable version output voltage range is VFB to 38V.
52KHz 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 40V.
Output load current is up to 2A.
SOP-8L, SOP-8L-EP, TO252-5L and TO263-5L Pb-Free packages.
Low power standby mode.
Built-in switching transistor on chip.
