CYW43353

2. Power Supplies and Power Management

2.1 Power Supply Topology

One buck regulator, multiple LDO regulators, and a power management unit (PMU) are integrated into the CYW43353. All regulators
are programmable via the PMU. These blocks simplify power supply design for Bluetooth and WLAN functions in embedded
designs.

A single VBAT (3.0V to 4.8 DC maximum) and VIO supply (1.8V to 3.3V) can be used, with all additional voltages being provided by
the regulators in the CYW43353.

Two control signals, BT_REG_ON and WL_REG_ON, are used to power up the regulators and take the respective section out of
reset. The CBUCK CLDO and LNLDO power up when any of the reset signals are deasserted. All regulators are powered down only
when both BT_REG_ON and WL_REG_ON are deasserted. The CLDO and LNLDO may be turned off and on based on the
dynamic demands of the digital baseband.

The CYW43353 allows for an extremely low power-consumption mode by completely shutting down the CBUCK, CLDO, and
LNLDO regulators. When in this state, LPLDO1 and LPLDO2 (which are low-power linear regulators that are supplied by the system
VIO supply) provide the CYW43353 with all the voltages it requires, further reducing leakage currents.
