IC TPS 51125

NEW IC TPS51125 TPS51125A 51125 QFN24 TIDAK GARANSI Description: The TPS51125 is a cost-effective, dual-synchronous buck controller targeted for notebook system power supply solutions. The device provides 5-V and 3.3-V LDOs and requires few external components. The 270-kHz VCLK output can be used to drive an external charge pump, thus generating gate drive voltage for the load switches without reducing the efficiency of the main converter. Features: Wide Input Voltage Range: 5.5 V to 28 V Output Voltage Range: 2 V to 5.5 V Built-In 100-mA, 5-V and 3.3-V LDO With Switches Built-In 1% 2-V Reference Output With or Without Out-of-Audio Mode Selectable Light-Load and PWM-Only Operation Internal 1.6-ms Voltage Servo Soft-Start Adaptive On-Time Control Architecture With Four Selectable Frequency Setting 4500 ppm/ xC2C RDS(on) Current Sensing Built-In Output Discharge Powergood Output Built-In OVP/UVP/OCP Thermal Shutdown (Nonlatch) QFN, 24-Pin (RGE)
