NXP Semiconductors TEA1211HN
The TEA1211HN is a fully integrated auto-up/down DC/DC converter circuit with I2C-bus interface. The combination of auto-up/down DC/DC conversion, high efficiency and low switching noise makes the TEA1211HN well suited to supply a power amplifier in a cellular phone. The output voltage can be I2C-bus programmed to the exact voltage needed to achieve a certain output power level with optimal system efficiency, thus enlarging battery lifetime.| Part No. | TEA1211HN |
