Description
The QST1105 is a type of IC Chip under the Electronic Component Model, designed as a 20MHz X-EMI™- enabled step-down regulator optimized for power low voltage rails from 2.7 to 5.5V input voltage. It features X-EMI™ inductor technology, which enables inductors to be drawn directly on the PC board. This technology meets or exceeds the EMI performance of chip inductors and eliminates the need for discrete inductors.
