TC1303B - (TC1303 / TC1304) 500 mA Synchronous Buck Regulator

Download the TC1303B datasheet PDF. This datasheet also covers the TC1303A variant, as both devices belong to the same (tc1303 / tc1304) 500 ma synchronous buck regulator family and are provided as variant models within a single manufacturer datasheet.

General Description

The TC1303/TC1304 combines a 500 mA synchronous buck regulator and 300 mA Low-Dropout Regulator (LDO) with a power-good monitor to provide a highly integrated solution for devices that require multiple supply voltages.

Key Features

  • Dual-Output Regulator (500 mA Buck Regulator and 300 mA Low-Dropout Regulator).
  • Power-Good Output with 300 ms Delay www. DataSheet4U. com.
  • Total Device Quiescent Current = 65 µA, Typ.
  • Independent Shutdown for Buck and LDO Outputs (TC1303).
  • Both Outputs Internally Compensated.
  • Synchronous Buck Regulator: - Over 90% Typical Efficiency - 2.0 MHz Fixed-Frequency PWM (Heavy Load) - Low Output Noise - Automatic PWM to PFM mode transition - Adjustab.
