AT5802
Preliminary
4-Channel driver + Power Controller
Description
The AT5802 is a 4-channel driver and power
controller for portable CD players on a single
chip. The driver block power supply uses the
on-chip switching regulator, making this
component an ideal choice for low-power sets.
Applications
Disc-man
Portable compact disc players (CDP)
Portable Mini disc player (MD)
Other portable compact disc media
