Description
The LM5177 is a four switch buck-boost controller.
The device 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 high efficiency with low output loads due to its low quiescence currents.
Features
- Wide input range from 3.5V to 60V (85V absolute maximum).
- Minimum 2.8V when V(BIAS) > 3.5V.
- Output voltage from 3.3V to 60V.
- Low shutdown IQ of 3μA.
- Low operating IQ of 60μA.
- 3% reverse current limit accuracy for precise charging currents.
- Average input and output current monitor or limiter.
- Dynamic output voltage tracking for PWM or analog input signals.
- Power save mode (PSM) selectable for high light load efficie.
