Filterless High Efficiency 1.5W Class D

Mono Amplifier

The ISL99201 is a fully integrated high efficiency class-D

mono amplifier. It is designed to maximize performance for

mobile phone applications. The application circuit requires a

minimum requirement of external components and operates

from a 2.4V to 5.5V input supply. It is capable of delivering

1.4W of continuous output power with less than 1% THD+N

driving a 8Ω load from a 5V supply.

The ISL99201 features a high-efficiency, low-noise

modulation scheme. It operates with 86% efficiency at

400mW into 8Ω and has a signal-to-noise ratio (SNR) that is

better than 95dB. The ISL99201 has a micro-power

shutdown mode with a typical shutdown current of 200nA.

Shutdown is enabled by applying a logic low to the SD pin.

The architecture of the devices allows it to achieve very low

level of pop-and-click. This minimizes voltage glitches at the

output during turn-on and turn-off, thus reducing audible

noise on activation and deactivation.

The fully differential input of the ISL99201 provides excellent

rejection of common mode noise on the input typically 75dB.

EMI suppression is achieved by SRC (Slew Rate Control).

The ISL99201 oscillator can be synchronized to an external

clock through the SYNC input, allowing the switching

frequency to be externally defined. The SYNC input also

allows multiple ISL99201 to be cascaded and frequency

locked; minimizing interference due to clock intermodulation.

SYNC is available only in DFN version.

The ISL99201 also has excellent rejection of power supply

noise, including noise caused by GSM transmission bursts

and RF rectification. PSRR is typically 75dB at 217Hz. There

will be 4 versions of the part; they will consist of three fixed

gain settings (6dB, 9.6dB, 12dB) and one user

programmable gain setting (need external resistors).

The ISL99201 has built-in thermal shutdown and output

short-circuit protection.
