SC2612E
500kHz Step-Down DC/DC Converter
Features
Applications
Revision: October 12, 2004
Typical Application Circuit
The SC2612E is a voltage mode switcher designed for
low cost, “point of use” voltage conversion. SC2612E is
available with fixed switching frequencies of 500kHz.
The SC2612E has soft start and enable functions and is
short circuit protected. The output of the switcher may
be set anywhere between 0.8V and 75% of Vin. Short
circuit protection is disabled during start-up to allow the
output capacitors time to fully charge.
Operating frequency of 500kHz
Input supply of 4.5V to 15V
0.5A Drive current for up to 10A output
Output voltages down to 0.8V
Overcurrent protection and soft start
