Advanced Analog Technology, Inc. AAT1101 Series Details are subject to change without notice TRIPLE OUTPUT TFT LCD PWM CONTROLLER Features General Description z Complete PWM Power Control Circuitry The z Precision Reference: 1.25V±1% (25 o C ) triple-channel pulse width modulation (PWM) solution z Low Operating Voltage: 2.5V to 6.5V z Under-Voltage Lockout Protection z 5V or 3.3V Selectable Over Voltage series provide for the power supply of LCD displays. an integrated These devices offer system engineers the flexibility to tailor-make the power supply circuitry for specific applications. Each channel contains its own error amplifier, PWM Lockout Protection (AAT1101/A only) comparator, dead–time control (DTC) and output driver. AAT1101/AAT1101A/AAT1101C: 500kHz Fixed AAT1101B: 50k~1MHz Programmable AAT1101 The under-voltage protection, over voltage protection, power sequence control, shutdown control circuit, z Internal Power Up Sequence Control z Totem Pole Output circuits are the common features of the three channels. z Output Short Circuit Protection The AAT1101 series contain two exclusive boost z Low Dissipation Current: 2.5mA circuits at CH1, CH3 and an exclusive buck_boost (f=500kHz, Duty=50%) circuit at CH2. AAT1101’s Power Up sequence initiates oscillator, short circuit protection, and voltage reference at CH1 then CH2 and finally CH3. AAT1101A/C’s Power Up sequence acts in the order of CH2, CH3, and Pin Configuration then CH1. AAT1101B’s Power Up sequence starts from CH2, CH1, and then CH3. TOP VIEW At the completion of IE2 1 16 SHDN the Power Up sequencing, the SCP pin stays low and PRDB 2 15 IE3 enters the Wait State of short circuit protection. Power VDD 3 14 IE1 Up sequencing delay and short circuit protection delay OUT2 4 13 EO 1 are set by connecting a capacitor to the SCP pin.
