Power supply and boost IC for class-H power amplifier
s Overview
A BTL 50 W × 2-channel (maximum. 75 W × 2-
channel) class-H power amplifier can be made up by com-
bining the power supply boost amplifier AN7077Z and
the single power supply BTL audio power amplifier
AN7194Z, and it is possible to make a low consumption
power system.
s Features
• Incorporating various protection circuits
• Built-in standby circuit
• Peak detection circuit : Limits class-H operation at high
frequency
• Built-in timer circuit
If a current larger than allowable value continues to flow
into the power supply transformer, this circuit stops the
class-H operation to prevent the transformer from dam-
age by a fire.
• Built-in mute function
• Built-in LED driver
s Applications
• Miniature audio component, CD player radio cassette,
karaoke and other audio equipment
