200KHz, 1.5A PWM Buck DC/DC Converter
™ GENERAL DESCRIPTION
The APE1720 series are monolithic IC designed for a step-down DC/DC converter,
and own the ability of driving a 1.5A 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 V_FB is down below 0.5V, the switching frequency will be reduced. The
APE1720 series operates at a switching frequency of 200KHz thus allow smaller sized
filter components than what would be needed with lower frequency switching
regulators. Other features include a guaranteed +3% tolerance on output voltage
under specified input voltage and output load conditions, The chips are available in a
standard 8-lead SOP package.
™ FEATURES
- Output voltage: adjustable output version.
- Adjustable version output voltage range: 0.75V to 22V+3%.

- Voltage mode non-synchronous PWM control.
- Thermal-shutdown and current-limit protection.
- ON/OFF shutdown control input.
- Operating voltage can be up to 24V.
- Output load current: 1.5A.
- SOP-8L Pb-Free packages.
- Low power standby mode.
- Built-in switching transistor on chip.
