XC9246/XC9247 Series ETR05024-006 16V Driver Transistor Built-In Step-Down DC/DC Converters ■GENERAL DESCRIPTION ☆GreenOperation-compatible XC9246/XC9247 series is a 16V step-down DC/DC converter with a built-in driver transistor. The series provides high efficiency, and a stable power supply with output currents up to 1A. The series is designed for use with small ceramic capacitors. The series has a 1.0V reference voltage, and using externally connected resistors, the output voltage can be set freely. With an internal switching frequency of 1.2MHz, small external components can be used. The soft-start time is internally set to 1.5ms (TYP.), but can be adjusted to set a longer time using an external resistor and capacitor.
