New 16V, 1A Step-Down DC/DC Converter
The new XC9246/47 series is a non-synchronous step-down DC/DC converter with internal LDMOS N-ch driver that is able to handle input voltages up to 16V and as low as 4.5V. Highly efficient, stable power supplies, with output currents up to 1A can be realized using only a coil, diode, and two ceramic capacitors connected externally.
The XC9246/47 series has a 1.0V (±1.5%) reference voltage, and using externally connected resistors, the output voltage can be set freely within a range of 1.2V to VIN.
The soft-start time is internally set to 1.5msec but can be adjusted externally using a simple RC circuit.
Available in a space saving USP-6C package or SOT-26W.
