10 Power Control and Regulation

For greater power efficiency the CSR8635 QFN contains 2 switch-mode regulators:

■ 1 generates a 1.80V supply rail with an output current of 185mA, see Section 10.1.

■ 1 generates a 1.35V supply rail with an output current of 160mA, see Section 10.2.

■ 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.

CSR8635 QFN contains 4 LDO linear regulators:

■ 3.30V bypass regulator, see Section 10.4.

■ 0.85V to 1.20V VDD_DIG linear regulator, see Section 10.5.

■ 1.35V VDD_AUX linear regulator, see Section 10.6.
