10 Power Control and Regulation
For greater power efficiency the CSR8615 QFN contains 2 switch-mode regulators:
â– 1 generates a 1.80V supply rail with an output current of 185mA, see Section 10.1.
â– 1 generates a 1.35V supply rail with an output current of 160mA, see Section 10.2.
â– Combining the 2 switch-mode regulators in parallel generates a single 1.80V supply rail with an output
current of 340mA, see Section 10.3.
CSR8615 QFN contains 4 LDO linear regulators:
