TPS62880QFWRADRQ1

TPS62880-Q1, TPS62881-Q1, TPS62882-Q1, and TPS62883-Q1 are a family of pin-compatible 12A, 20A, 24A, and 30A synchronous dual-phase step-down DC/DC converters for automotive applications. The TPS6288x-Q1 employs an enhanced DCS-Control architecture, combining fast transient response with fixed-frequency operation. Dual-phase operation reduces input and output voltage ripple and allows the use of smaller inductors per phase. Under medium to heavy loads, the device operates in PWM mode and automatically transitions to discontinuous conduction mode under light loads, maintaining high efficiency across the full load current range. The device can also be forced into PWM mode for minimum output voltage ripple. The device provides 0.5% DC output voltage accuracy over the recommended input voltage and temperature range. Differential remote sensing enables precise voltage regulation at the load. The I2C-compatible interface is functional as long as the supply voltage exceeds the UVLO threshold. This interface offers a wide range of control, monitoring, and alert functions, such as voltage monitoring and temperature alerts. Dynamic voltage scaling allows load power consumption to adapt to application performance requirements. The default startup voltage is selectable via the VSELx pins. The switching frequency is factory-preset at 2.25MHz, with options for 1.5MHz, 2.5MHz, or 3MHz. The TPS6288x-Q1 can synchronize to an external clock. Stacked operation allows up to five devices to operate in parallel, supporting a total output current of up to 150A. The PS pin works in conjunction with the SYNC_OUT pin to designate a device as a primary or secondary. The phase shift of secondary devices is defined by the VSEL1 and VSEL2 pins and can be set to 30°, 60°, 90°, or 120°.
