Description
General part information
TPS40170-EP Series
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 an 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 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 within 1% accuracy. Additionally, the controller implements a novel scheme of bidirectional 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.
