3.4.2 Register VOUT (Target Address: 0x2A; Register Address: 0x03; Default: 0x5C)

Table 4-3 shows the STATUS register.

Return to Section 3.4.

This register contains the device status. A read operation to this register clears the status bits. This register is volatile, so the register loses contents if the voltage on the VIN pin becomes less than the UVLO threshold or a low logic level is applied to the EN pin.

Table 3-3 Register VOUT Field Descriptions
BitFieldTypeResetDescription
7:0VOUT[7:0]R/W0X5C

These bits set the output voltage

Output voltage = 1.000 + (VOUT[7 :0] × 0.025) V when 0x00<=VOUT[7 :0]<=0xB4;

Output voltage = 5.5 V when 0xB5<=VOUT[7 :0]<=0xFF
