PWM CurrentMode
Controller for HighPower
Universal OffLine Supplies
Housed in a SOIC8 or PDIP7 package, the NCP1216 represents
an enhanced version of NCP1200 based controllers. Due to its high
drive capability, NCP1216 drives large gatecharge MOSFETs, which
together with internal ramp compensation and builtin frequency
jittering, ease the design of modern ACDC adapters.
With an internal structure operating at different fixed frequencies,
the controller supplies itself from the highvoltage rail, avoiding the
need of an auxiliary winding. This feature naturally eases the designer
task in some particular applications, e.g. battery chargers or TV sets.
Currentmode control also provides an excellent input audio
susceptibility and inherent pulsebypulse 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 socalled
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 NCP1216 features an efficient protective circuitry, which in
presence of an over current condition disables the output pulses while
the device enters a safe burst mode, trying to restart. Once the default
has gone, the device autorecovers.
