TEA1705/1R

Power Supply Controllers, Monitors Overview

The TEA1705/1R is a secondary-side controller designed for use in GreenChip mobile charging solutions. It functions as an instantaneous controller that detects load-level changes to generate primary-side wake-up interrupts, enabling efficient burst-mode operation when paired with the TEA1720A primary-side SMPS controller. This configuration supports fast transient response and allows for reduced output capacitance, contributing to compact charger designs with low standby power consumption.
