Description
- The LM3279EVM evaluation board has LM3279 with its essential passive components to show buck boost capability and also it enables the user to test part in all the modes of operation. The LM3279 is a buck boost DC to DC converter designed to generate output voltages above or below a given input voltage and is particularly suitable for power amplifiers operating from single cell Li Ion batteries. It has four modes of operation, PWM, PFM, standby and shutdown. During normal conditions, LM3279 operates in full synchronous PWM mode, providing seamless transitions between buck and boost operating regimes. Energy saving PFM mode increases efficiencies and current savings during low power RF transmission modes. For high transmit power, device operates in PWM buck or boost mode, whereas device can transition between PWM and PFM modes during low power transmit. The LM3279 can be controlled either via included MIPI RFFE interface or analog control from external MCU, offering design flexibility.
- High efficiency PFM and PWM modes with internal seamless transition
- Adjustable output voltage
- RFFE digital control from 0.4V to 4.2V
- Analog control from 0.6V to 4.2V
- Seamless buck boost mode transition
- 1A maximum load capability for VBATT >= 3.2V, VOUT = 3.6V
- Fast output voltage transition from 0.8V to 4.0V in 20uSec
- High efficiency of 95%
- Internal compensation
- 2.4MHz typical switching frequency
- ESD sensitive device, take proper precaution while handling the device.
- This evaluation module is not a finished electrical equipment and not intended for consumer use.
