Preliminary
PJ2596
150KHz, 3A PWM Buck Switching Regulator
1-6
2004/07.rev.B
The PJ2596 is a monolithic integrated circuit that
provide all the active function for a step-down
switching regulator, capable of driving a 3A load without
additional transistor component. The external shutdown
function can be controlled by TTL logic level and then into
standby mode. The internal compensation makes feedback
control have good line and load regulation without external
design. Regarding protected function, thermal shutdown is to
prevent over temperature operating from damage, and current
limit is against over current operating of the output switch.
The PJ2596 operates at a switching frequency of PJ2596 thus
allowing smaller sized filter components than what would be
needed with lower frequency switching regulators. Other
features include a guaranteed ±4% tolerance on output voltage
under specified input voltage and output load conditions, and
±15% on the oscillator frequency. The output version included
fixed 3.3V, 5V, 12V, and an adjustable type.
