Working Principle

The AES6288DR is an advanced non-synchronous buck converter with an integrated power switch, integrated advanced current sensing and loop compensation circuitry, integrated FET, and a dual-mode low ripple Burst-Mode control architecture. The device integrates a synchronous rectifier FET which allows the output current to be regulated by switches which operate in Alternate Phase/Complementary Mode.

The device utilizes a high-speed Pulse-Width Modulation (PWM) controller with dual-mode low-noise Burst-Mode switching. In Burst mode, the device is able to switch at a higher frequency, which allows the output voltage to be regulated by a higher loop bandwidth. In addition, the device also implements an adjustable cycle-by-cycle current limit and output current monitoring with hysterisis.

The TLV62568DRLR also features an external low temperature coefficient resistor for programmable output voltage, an integrated soft start feature which lowers inrush current at start-up and allows for smooth start of the circuit. The input voltage range is 2.9 V to 5.5 V, output voltage is adjustable and can range from 0.8 V to 5.5 V.

The TLV62568DRLR is the ideal solution for applications where high efficiency, low cost, small size and low power dissipation are essential.
