The TPS62880-Q1, TPS62881-Q1, TPS62882-Q1, and TPS62883-Q1 are a family of pin-to-pin 12A, 20A, 24A, and 30A synchronous, dual-phase, step-down DC/DC converters. The TPS6288x-Q1 implement an enhanced DCS-Control scheme that combines fast transient response with fixed frequency operation. Dual-phase operation reduces the input and output voltage ripple and also enables the use of smaller inductors per phase. At medium to heavy loads, the devices operate in Pulse Width Modulation (PWM) mode and automatically enter discontinuous conduction mode at light load to maintain high efficiency over the entire load current range. The devices can also be forced into PWM mode operation for smallest output voltage ripple. The devices provide 0.5% DC output voltage accuracy across the recommended input voltage and temperature range. Differential remote sense allows for accurate voltage control directly at the load. The I2C compatible interface is operational as long as the supply voltage is above the UVLO threshold. The interface offers several control, monitoring, and warning features, such as voltage monitoring and temperature warnings. Dynamic voltage scaling allows the load power consumption to adapt to the performance needs of the application. The default start-up voltage is selectable by the VSELx pins. The switching frequency is factory programmed to 2.25MHz with options for 1.5MHz, 2.5MHz, or 3MHz. The TPS6288x-Q1 can be synchronized to an external clock. Stacking allows to operate up to five devices in parallel to support a total output current of up to 150A. The PS pin along with the SYNC_OUT pin define a device as a primary or secondary device. The phase shift of the secondary devices is defined by the VSEL1 and VSEL2 pins to either 30°, 60°, 90°, or 120°. See the Device Options table for details.
