CRD44130-FB Datasheet (Cirrus Logic) - 20 W x 2 + 40 W x 1 PWM Amplifier Reference Design

CRD44130-FB, 20 W x 2 + 40 W x 1 PWM Amplifier Reference Design

The CRD44130-FB PWM amplifier demonstrates the CS44600 and CS44130 Cirrus Logic’s multi-channel all-digital PWM controller and power stage.

This reference design implements a multi-channel amplifier that delivers 20 W per channel into 8 Ω loads and 40 W into a 4 Ω load using a single +18 V supply (a
