ZHCSR16 September 2022 TPS544C26
ADVANCE INFORMATION
The TPS544C26 device offers VRRDY output that asserts high when the converter output is within the target. The VRRDY output stays low when the switching is disabled either by EN pin or through I2C (01h) OPERATION command. The VRRDY function is activated after the soft-start ramp is completed. The VRRDY output is an open-drain output and must be pulled up externally through a pull-up resistor (usually 10 kΩ). The recommended VRRDY pull-up resistor value is 1 kΩ to 100 kΩ.
