SM8172A Overview
VIN1 and VIN2 should have the same voltage potential. When the series regulator is not used, LDOUT pin should be open and not be connected to GND.
SM8172A Key Features
- Feedback-type current limiter to reduce output current when outputs are short-circuit
- Output voltage: 3.3V (available for optional setting from 2.1 to 3.6V by 0.1V-step)
- Maximum output current: 450mA
- Voltage accuracy: ± 2% (VIN = 5.0V, Ta = 25°C) I DC/DC converter
- Current-mode operation for excellent transient
- Output voltage: 0.8 to 1.8V
- Maximum output current: 900mA
- Operating frequency: 2MHz (typ)
- Voltage accuracy: ± 2%
- Reset detection voltage: 3.7V (typ) (available for optional setting from 3.2 to 4.2V by 0.1V-step)
