The AAT1100-T is one member of the AAT1100 family which is designed as the triple-channel PWM controller that provides an integrated triple-channel pulse-width-modulation (PWM) solution for the power supply of DC-DC system; this device AAT1100-T offers system engineer the flexibility to custom-make the power supply circuitry to a specific application. Each channel contains its own error amplifier, PWM comparator, dead-time control (DTC) and output driver.
Features of the AAT1100-T are:(1)complete PWM power control circuitry;(2)precision reference: 1.25 V +/- 1 %;(3)lowoperating voltage: 2.5 V to 7.0 V;(4)under-voltage lockout protection;(5)totem pole output;(6)output short circuit protection;(7)low dissipation current: 2.5 mA at 500 kHz and 50% duty cycle;(8)separate on / off control for CH1, CH3 pair and CH2 (refer to function table);(9)dead time control: 0 to 100 %;(10)wide operating frequency: 50 kHz to 1 MHz;(11)minimized external components.
The absolute maximum ratings of the AAT1100-T can be summarized as:(1)Reference Voltage: 1.237 to 1.263 V;(2)Short Circuit Output Current: -2 to -30 mA;(3)Output Regulation: 1 mV;(4)Reference Voltage Change with Temperature:15 mV;(5)Input Offset Voltage: 15 mV.
