Description
The MP1474 is a high-frequency, synchronous, rectified, step-down, switch-mode converter with built-in power MOSFETs. It offers a verycompact solution to achieve a 2A continuous output current with excellent load and line regulation over a wide input supply range. The MP1474 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 MP1474 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
- Power-Save Mode at Light Load
- Internal Soft-Start
- Power Good Indicator
