NJW4170U2-A regulator equivalent, current mode control high speed frequency internal 1a mosfet switching regulator.
Oscillating Frequency
2.4MHz typ. (A ver.)
2.1MHz typ. (B ver.)
Minimum ON time
80ns typ.(A ver.)
85ns typ.(B ver.)
Current mode Control
External Clock Synchroniz.
Also, it has a soft start function, an external clock synchronization function, an over current protection and a therma.
The NJW4170 is a high speed oscillating frequency buck converter with 40V/1A MOSFET. Current mode control and built-in phase compensation circuit minimize external parts and contribute to using a Low ESR Output Capacitor(MLCC) within wide input range.
