TPS65040 描述

The TPS65040 is an advanced RF power management chip for cellular phones, providing a highly optimized solution for UMTS/WCDMA/GSM power amplifier applications. This solution improves efficiency by voltage control of the power amplifiers, saving power to prolong battery life. The TPS65040 features buck boost DC/DC converters suited for applications requiring up to 550-mA output current while dynamically adjusting output voltage from 0.8 V to 4.2 V with a fast settling time, high performance 8-channel LDO regulators, 8bit DAC, 12bit ADC and clock distribution buffers of 26 MHz VCTCXO. Each block can be controlled by serial interface and external pins. The TPS65040 offers material cost savings and small size, using a compact 5 mm × 5 mm MicroStar JuniorTM package.
