NOTES:

6. Parameters with MIN and/or MAX limits are 100% tested at +25C, unless otherwise specified. Temperature limits established by characterization

and are not production tested.

7. Typical values are for TA = +25°C and VIN = 3.3V.

8. LSB = I V255 - V1 I / 254. V255 and V1 are the measured voltages for the DCP register set to FF hex and 01 hex, respectively.

9. DNL = I Vi+1 - Vi I / LSB-1, i ∈ [1, 255]

10. ZS error = (V1- VMAX)/LSB. VMAX = (VAVDD * R2) * [1-2 * R1/(256 * 20 * RSET)]/(R1 + R2)

11. FS error = (V255 - VMIN)/LSB. VMIN = (VAVDD * R2) * [1-256 * R1/(256 * 20 * RSET)]/(R1 + R2)

12. Established by design. Not a parametric spec.

13. Boost will stop switching as soon as boost output reaches OVP threshold.

14. Compliance to limits is assured by characterization and design.
