BD9325EFJ, BD9326EFJ and BD9327EFJ are step-down regulators that integrate a low resistance (0.16 ohm/ 0.12ohm / 0.11ohm) high side N-channel MOSFET. Output current levels reach 2A / 3A / 4A in continuous operation over a wide supply voltage range (4.75V~18V). Current mode operation provides fast transient response and easy phase compensation.
Further features are: Low-ESR output ceramic capacitors operation, low standby current during shutdown mode, 380kHz internally generated clock frequency and a low feedback voltage of 0.9V ±1.5%.
The devices are also equipped with protection functions like under-voltage lockout, thermal shutdown and over-current limitation.
