TPS65400RGZR Description

Short technical summary and product information.

The Texas Instruments TPS65400RGZR is a versatile power management IC designed for various applications requiring efficient DC-DC conversion. This device integrates a quad synchronous buck converter, capable of handling an input voltage range from 4.5 V to 18 V.

 

Key electrical specifications include adjustable output voltages ranging from 0.8 V to 16 V. Two of the outputs (SW1, SW2) can deliver up to 4 A each, while the other two (SW3, SW4) support up to 2 A each. The switching frequency is adjustable from 275 kHz to 2.2 MHz, allowing for optimization of performance and size. The converter boasts high efficiency, up to 95% for each switching regulator, and features like I2C and PMBus interfaces for control and monitoring.

 

Designed for surface mounting, the TPS65400RGZR comes in a 48-VQFN (7x7 mm) package with an exposed pad for enhanced thermal performance. It operates within a temperature range of -40°C to 85°C. Integrated protection features include undervoltage lockout (UVLO), overcurrent protection (OCP), overvoltage protection (OVP), and overtemperature protection (OTP). The device also supports features like prebias startup and soft-start adjustment.
