It is designed to maximize performance for Filterless class D with efficiency > 86% at 400mW mobile phone applications. The application circuit requires a minimum requirement of external components and operates Click-pop suppression from a 2.4V to 5.5V input supply. It is capable of delivering Slew rate control 1.4W of continuous output power with less than 1% THD+N Spread spectrum switching driving a 8 load from a 5V supply. Optional SYNC pin for master/slave operation without The ISL99201 features a high-efficiency, low-noise interface modulation scheme. It operates with 86% efficiency at 400mW into 8 and has a signal-to-noise ratio (SNR) that is 1.4W into 8 with less than 1% THD+N better than 95dB. The ISL99201 has a micro-power 2.4V to 5.5V single supply voltage shutdown mode with a typical shutdown current of 200nA. Shutdown is enabled by applying a logic low to the SD pin. Built-in resistors to reduce board component count Only one external component required (Fixed gain mode) The architecture of the devices allows it to achieve very low level of pop-and-click. This minimizes voltage glitches at the Short circuit and thermal protection output during turn-on and turn-off, thus reducing audible noise on activation and deactivation. Gain programmable 6dB, 9.6dB, 12dB and User programmable The fully differential input of the ISL99201 provides excellent rejection of common mode noise on the input typically 75dB. Pb-Free (RoHS compliant) EMI suppression is achieved by SRC (Slew Rate Control). Applications The ISL99201 oscillator can be synchronized to an external clock through the SYNC input, allowing the switching Mobile phones frequency to be externally defined. The SYNC input also MP3 players allows multiple ISL99201 to be cascaded and frequency locked minimizing interference due to clock intermodulation. Portable gaming Portable electronics The ISL99201 also has excellent rejection of power supply noise, including noise caused by GSM transmission bursts Educational toys 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. FN6742 Rev 2.00 Page 1 of 11 November 1, 2013ISL99201 Ordering Information PACKAGE PART PART GAIN SETTING TEMP.
