 PS1711/2/3
Integrated Driver and MOSFET Module
 |
General Description
The PS171X series is an integrated gate driver and MOSFETs module for synchronous buck applications. The gate driver with embedded bootstrap switch to gain high switching frequency operation, 200kHz to 2MHz. The driver and MOSFETs are optimized for good efficiency in the synchronous buck converter. The driver features strong driving capability, robust control, adaptive deadtime control and low quiescent current. The MOSFETs feature low switching and conduction losses in the synchronous buck configuration. For switching loss, the high-side MOSFET is designed low capacitance to get lower gate charge. For conduction loss, the low-side MOSFET is designed low RON resistance.
The PS171X series provides 5V PWM input for compatibility with different controller. It also provides INTEL PS4 requirement, the PS4 exit time is 9.5μs.
The PS171X series is available in the space-saving QFN-31L 5x5 package and is rated over a -40°C to +125°C ambient temperature range. |
