NX2838CM - Brand New Microchip Technology IC Chips
-
Description
The NX2838CM is a two-phase PWM controller with an integrated FET driver designed for low voltage high current applications. This electronic component offers ripple cancellation for both the input and output. It uses differential remote sensing using either current sense resistor or inductor DCR sensing to achieve accurate current matching between the two channels. This eliminates errors caused by PCB board trace resistance. The NX2838CM also offers high drive current capability, accurate programmable droop, programmable switching frequency, and hiccup current limiting circuitry.
Specifications and Features
- Differential inductor DCR sensing eliminates layout parasitic issues
