New synchronous step-down converter, the HT74153. The device can operate with an input voltage range of 2.5V~6V and is thus suitable for use in products powered by 3 to 4 cell dry batteries or a single Li-battery. With an output current of up to 2A, the new device can provide a stable output voltage for driving high current load applications such as a low voltage DC motors or a laser diode. These features combine to ensure the device is suitable for portable products which include massagers, toys and laser projectors etc.
The HT74153 has a 100% duty cycle operation feature, extending the end product durability. If the battery voltage should become lower than the target output voltage, then the output voltage will track the input voltage. The HT74153 has a current consumption only 50μA under no load conditions.
