General Description
The CS3511 is a high-efficiency class-D PWM amplifier
that integrates on-chip over-current, under-voltage,
over-temperature protection, and error reporting. An on-
board regulator generates a 5 VDC supply used
to power the internal low-voltage analog and digital cir-
cuitry. The low RDS(ON) outputs can source peak cur-
rents up to 2.7 A, deliver high efficiency, allow a small
device package, and lower power supply voltage levels.
The CS3511 is available in a 32-pin QFN package in
Commercial grade (-10°C to +70°C). The CRD3511
customer reference design is also available. Please re-
fer to “Ordering Information” on page 24 for complete
ordering information.
