TPS5124 Datasheet Dual Channel Synchronous Step-down Pwm Controller

Manufacturer: Texas Instruments

Overview: TPS5124 ą DUAL CHANNEL, SYNCHRONOUS STEPĆDOWN PWM CONTROLLER SLUS571 − SEPTEMBER.

General Description

The TPS5124 is dual independent high efficiency synchronous step-down controller.

It supports a low-voltage/high-current power supply applica− tions that use either a 5-V or 12-V bus voltage.

Since both controllers of the TPS5124 operate 180 degree out-of-phase, the input current ripple is minimized resulting in a smaller input capacitance and reduced power supply cost.

Key Features

  • D High Efficiency.
  • No Current Sense Resistor Required, RDS(on) Overcurrent Detection with Temperature Compensation D Adjustable Output Voltage Down to 0.9 V D Voltage-Mode PWM Control: Maximum 500-kHz Operation D 180° Out-of-Phase Control D Individual Standby and Soft-Start for Each Channel.
  • Easy Power Sequencing D Overvoltage and Undervoltage Protection D Built-In Boot-Strap Diode D Built-In 5-V Linear Regulator D Accurate ± 1% 0.85-V Reference.
