UCD7242 Overview
Key Specifications
Package: QFN
Mount Type: Surface Mount
Pins: 32
Max Voltage (typical range): 18 V
Description
The UCD7242 is a complete power system ready to drive two independent buck power supplies (see Figure 1). High side MOSFETs, low side MOSFETs, drivers, current sensing circuitry and necessary protection functions are all integrated into one monolithic solution to facilitate minimum size and maximum efficiency.
