MP1494DJ是一个High-Efficiency, 2A, 16V, 500kHz Synchronous, Step-Down Converter。效率高达94%以上。
采用SOT23-8的引脚封装。
Description:
The MP1494 is a high-frequency, synchronous, rectified, step-down, switch-mode converter with built-in power MOSFETs. It offers a very compact solution to achieve a 2A continuous output current with excellent load and line regulation over a wide input supply range. The MP1494 has synchronous mode operation for higher efficiency over the output current load range. Current-mode operation provides fast transient response and eases loop stabilization. Full protection features include over-current protection and thermal shut down. The MP1494 requires a minimal number of readily-available standard external components, and is available in a space-saving 8-pin TSOT23 package.
Features:
• Wide 4.5V-to-16V Operating Input Range
• 100mΩ/40mΩ Low RDS(ON) Internal Power MOSFETs
• High-Efficiency Synchronous Mode Operation
• Fixed 500kHz Switching Frequency
• Synchronizes from a 200kHz-to-2MHz External Clock
• AAM Power-Save Mode
• Internal Soft-Start
• OCP Protection and Hiccup
• Thermal Shutdown
• Output Adjustable from 0.8V
• Available in an 8-pin TSOT-23 Package
