TD1484B - 3A 23V Synchronous Rectified Step-Down Converter

Key Features

  • The TD1484B is a monolithic synchronous buck regulator. The device integrates two 90mΩ MOSFETs, and provides 3A of continuous load current over a wide input voltage of 4.75V to 23V. Current mode control provides fast transient response and cycle-by-cycle current limit. An adjustable soft-start prevents inrush current at turn-on, and in shutdown mode the supply current drops to 1µA. The TD1484B regulates the output voltage in automatic PSM/PWM mode operation, depending on the outputcurrent, for.

Techcode® DATASHEET 3A 23V Synchronous Rectified Step-Down Converter TD1484B General Description Features The TD1484B is a monolithic synchronous buck regulator. The device integrates two 90mΩ MOSFETs, and provides 3A of continuous load current over a wide input voltage of 4.75V to 23V. Current mode control provides fast transient response and cycle-by-cycle current limit. An adjustable soft-start prevents inrush current at turn-on, and in shutdown mode the supply current drops to 1µA. The TD1484B regulates the output voltage in automatic PSM/PWM mode operation, depending on the outputcurrent, for high efficiency operation over light to full load current. This device, available in an SOP8-PP package, provides a very compact solution with minimal external components.
