TPS65263
- Operating input voltage range 4.5- to 18-V continuous output current 3 A/2 A/2 A
- I 2C controlled 7-bits VID programmable output voltage from 0.68 to 1.95 V with 10-mV voltage step for each buck
- I 2C controlled VID voltage transition slew rate
- I 2C read back power-good status, overcurrent warning for each buck
- I 2C read back die temperature warning
- I 2C compatible interface with standard mode (100 kHz) and fast mode (400 kHz)
- Feedback reference voltage 0.6 V ±1%
- Fixed 600-kHz frequency
- Dedicated enable and soft start pins for each buck
- Thermal overloading protection
The TPS65263 incorporates triple synchronous buck converters with 4.5- to 18-V wide input voltage range that encompassed most intermediate bus voltage operating off 5-, 9-, 12-, or 15-V power bus or battery. The converter, with constant frequency peak current mode, is designed to simplify its application while giving designers options to optimize the system according to targeted applications. The device operates in 600 kHz with 180° out-of-phase between buck1 and buck2, buck3 (buck2 and buck3 run in phase).
The initial startup voltage of each buck can be set with external feedback resistors. The output voltage of each buck can be dynamically scaled from 0.68 to 1.95 V in 10-mV step with I 2C controlled 7 bits VID. The VID voltage transition slew rate is programmable with 3-bits control through I 2C bus to optimize overshoot/undershoot during VID voltage transition.
Each buck in TPS65263 can be I 2C controlled for enabling/disabling output voltage, setting the pulse skipping mode (PSM) or force continuous current mode (FCC) at light load condition and reading the power good status, overcurrent warning and die temperature warning.
The TPS65263 features overvoltage, overcurrent, short-circuit, and overtemperature protection.
