Introduction

The TCC-303 is a three-output high-voltage DAC control IC designed specifically to control and bias onsemi passive tunable integrated circuits. These tunable capacitor control circuits are intended for use in mobile phones and dedicated RF tuning applications. Integrating onsemi tunable circuits in mobile phones can significantly improve antenna radiation performance. Tunable capacitors are controlled via a bias voltage ranging from 1 V to 24 V. The TCC-303 high-voltage PTIC control IC is designed to meet this requirement, providing three independent high-voltage outputs capable of simultaneously controlling up to three different tunable PTICs. The device is fully controlled via the MIPI RFFE digital interface.
