Housed in an SO--8 or PDIP--7 package, the NCP1217 represents
the enhanced version of the NCP1203--based controllers. Due to its
high drive capability, NCP1217 drives large gate--charge MOSFETs,
which together with internal ramp compensation and built--in
overvoltage protection, ease the design of modern AC/DC adapters.
NCP1217 offers a true alternative to UC384X--based designs.
With an internal structure operating at different fixed frequencies
(65–100–133 kHz), the controller features a high--voltage startup FET,
which ensures a clean and loss less startup sequence. Its current--mode
control topology provides an excellent input audio--susceptibility and
inherent pulse--by--pulse control. Internal ramp compensation easily
prevents subharmonic oscillations from taking place in continuous
conduction mode designs.
When the current setpoint falls below a given value, e.g. the output
power demand diminishes, the IC automatically enters the so--called
skip cycle mode and provides excellent efficiency at light loads.
Because this occurs at a user adjustable low peak current, no acoustic
noise takes place.
The NCP1217 features two efficient protective circuitries: 1) In
presence of an overcurrent condition, the output pulses are disabled
and the device enters a safe burst mode, trying to restart. Once the
default has gone, the device auto--recovers. 2) If an external signal
(e.g. a temperature sensor) pulls Pin 1 above 3.2 V, output pulses are
immediately stopped and the NCP1217 stays latched in this position.
Reset occurs when the V CC collapses to ground, e.g. the user unplugs
the power supply.
