Texas Instruments TPS40170RGYT

TPS40170 is a full-featured, synchronous PWM buck controller that operates at an input voltage between 4.5 V and 60 V and is optimized for high-power density, high-reliability DC-DC converter applications. The controller implements voltage-mode control with input voltage feed-forward compensation that enables instant response to input voltage change. The switching frequency is programmable from 100 kHz to 600 kHz.

The TPS40170 has a complete set of system protection and monitoring features such as programmable undervoltage lockout (UVLO), programmable overcurrent protection (OCP) by sensing the low-side FET, selectable short-circuit protection (SCP) by sensing the high-side FET and thermal shutdown. The ENABLE pin allows for system shutdown in a low-current (1 µA typical) mode. The controller supports pre-biased output, provides an open-drain PGOOD signal, and has closed-loop soft-start, output voltage tracking and adaptive dead-time control.

TPS40170 provides accurate output voltage regulation through 1% ensured accuracy. Additionally, the controller implements a novel scheme of bi-directional synchronization with one controller acting as the master and other downstream controllers acting as slaves synchronized to the master in-phase or 180° out-of-phase. Slave controllers can be synchronized to an external clock within ±30% of the free-running switching frequency.
