4.5V 至 18V 输入电压、3A/2A/2A 输出电流降压转换器,具有通过 I2C 控制的 DVS 32-VQFN
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 I2C controlled 7 bits VID. The VID voltage transition slew rate is programmable with 3-bits control through I2C bus to optimize overshoot/undershoot during VID voltage transition.
Each buck in TPS65263 can be I2C 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.
