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.
