Application note:
The LM251772 is a four switch Buck-Boost controller. It provides a regulated output voltage if the input voltage is higher, equal or lower than the adjusted output voltage. In power save mode the device supports very high efficiency over the complete operation range of the output. The output voltage and average current can be dynamically programmed via the integrated I2C interface. The configuration range for output voltage and average current meet the USB-PD standard requirements. The integrated DRV pin can control a disconnect FET to support dual role port (DRP) requirements.
- Input range from 3.5V to 36V
- Dynamical Vo programming via I2C from:
- 3.3V up to 48V in 20mV steps
- 1V up to 24V in 10mV steps
- Peak current regulation control
- Small voltage transition ripple over all operating modes
- Shut down quiescent current 3µA
- Operating quiescent current 60µA
- Drive (DRV) pin for dual role port power path
- Push-Pull output for fast pMOS FET control
- Configurable as charge pump driver stage for nMOS FET
- Operation mode selection for high efficiency in light load and high load conditions:
- Power save mode (Single Pulse/µSleep)
- Automatic conduction mode
- Integrated high voltage supply LDO
- Auxiliary high voltage LDO for PD-controller supply
- Integrated full-bridge gate drive
- 2A peak current capability
- Bootstrap over and under-voltage protection
- Integrated boot-strap diode
- Fixed frequency independent from operating mode (boost, buck-boost, buck)
- Forced PWM mode selectable
- Switching frequency from 100kHz to 600kHz
- External clock synchronization and clock output
- Average input or output current sensor
- Programmable from 0.5A to 7A in 50mA steps
- I2C Interface readout of monitoring features
- Commercial temperature range (Tj = 0°C to 70°C)
