The controller implements voltage-mode control with • Voltage Mode Control With Voltage Feed Forward input voltage feed-forward compensation that enables • Programmable Frequency Between 100 kHz and instant response to input voltage change. The 600 kHz switching frequency is programmable from 100 kHz to • Bi-directional -Frequency Synchronization With 600 kHz. Master/Slave Option The TPS40170 has a complete set of system • Low-side FET Sensing Overcurrent Protection and protection and monitoring features such as High-Side FET Sensing Short-Circuit Protection programmable undervoltage lockout (UVLO), With Integrated Thermal Compensation programmable overcurrent protection (OCP) by sensing the low-side FET, selectable short-circuit • Programmable Closed Loop Soft-Start protection (SCP) by sensing the high-side FET and • Supports Pre-Biased Outputs thermal shutdown. The ENABLE pin allows for • Thermal Shutdown at 165°C with Hysteresis system shutdown in a low-current (1 µA typical) • Voltage Tracking mode. The controller supports pre-biased output, provides an open-drain PGOOD signal, and has • Powergood closed-loop soft-start, output voltage tracking and • ENABLE with 1-µA Low Current Shutdown adaptive dead-time control. • 8.0-V and 3.3-V LDO Output TPS40170 provides accurate output voltage • Integrated Bootstrap Diode regulation through 1% ensured accuracy. • 20-Pin 3.5 mm × 4.5 mm VQFN (RGY) Package Additionally, the controller implements a novel scheme of bi-directional synchronization with one • Create a Custom Design Using the TPS40170 controller acting as the master and other downstream with the WEBENCH Power Designer controllers acting as slaves synchronized to the master in-phase or 180° out-of-phase. Slave 2 Applications controllers can be synchronized to an external clock • POL Modules within ±30% of the free-running switching frequency. • Wide Input Voltage, High-Power Density DC - DC (1) Device Information Converters for Industrial, Networking and Telecom PART NUMBER PACKAGE BODY SIZE (NOM) Equipment TPS40170 VQFN (20) 3.50 mm × 4.50 mm (1) For all available packages, see the orderable addendum at the end of the datasheet.
