Note:
The hardware design uses the internal LDO regulator (not the SMPS DC-DC), we chose not to imple-
ment the internal BUCK regulator because in our experience, when a baery is reaching end of life
the voltage it provides starts to drop and then avalanches in a non linear curve in a short me.
It is only at this stage that the SMPS provides a benet over and above the LDO regulator, and con-
sidering the cost of the large inductor the SMPS requires its not jused for a marginal extension in
me the circuit obtains
If the SMPS is required please contact our Sales Dept
