TPS5602IDBTG4

双通道，快速，高效率控制器的DSP处理能力 DUAL, FAST, HIGH EFFICIENCY CONTROLLER FOR DSP POWER

description

The TPS5602 is a dual-channel synchronous buck switch-mode power supply controller featuring very fast feedback control and minimized component count. By using the hysteretic control method, it is ideal for high-transient current applications, such as ’C6000 and multiple ’C54x DSPs. The TPS5602 is designed specifically for DSP applications that require high efficiency. Since both channels are independent, the up and down power sequencing can be easily achieved by properly setting the standby pins. The wide input voltage and adjustable output voltage make the TPS5602 suitable for many applications.
