Texas Instruments TPS563212

Description

The TPS563212 is a single, advanced emulated current mode (AECM) control, synchronous buck converter,that is able to deliver 3-A continuous output current, providing selectable Eco-mode operation or FCCM operation and a selectable power-good indicator or external soft start by the configuring the MODE pin. Powersequencing is possible by correctly configuring the enable, power-good indicator, or external soft start. Thedevice implements an AECM control, which can get fast transient response with fixed frequency. The fast transient response results in low voltage drop and fixed frequency brings a better jitter permanence and predictable frequency for EMI design. The optimized internal compensation network minimizes the external component counts and simplifies the control loop design over a wide voltage output range.
