R2J20701NP

Notes: 1. Pt(25) represents a PCB temperature of 25°C, and Pt(100) represents 100°C.
2. Rated voltages are relative to voltages on the SGND and PGND pins.
3. For rated current, (+) indicates inflow to the chip and () indicates outflow.
4. Ratings for which "ac" is indicated are limited to within 100 ns.

This all-in-one SiP for POL (point-of-load) applications is a multi-chip module incorporating a high-side MOS FET,
low-side MOS FET, and PWM controller in a single QFN package. The on and off timing of the power MOS FET R2J20701NP is optimized by the built-in driver circuit, making this device suitable for large-current high-efficiency buck converters.

In a simple peak-current mode topology, stable operation is obtained in a closed power loop, and a fast converter is
easily realized with the addition of simple components. Furthermore, the same topology of R2J20701NP can be applied to realize converters for parallel synchronized operation with current sharing, and two-phase operation.

The package also incorporates a high-side bootstrap Schottky barrier diode (SBD), eliminating the need for an external SBD for this purpose.
