NCP1216, NCP1216A
PWM Current鈭扢ode
Controller for High鈭扨ower
Universal Off鈭扡ine Supplies
Housed in a SOIC鈭? or PDIP鈭? package, the NCP1216 represents
an enhanced version of NCP1200 based controllers. Due to its high
drive capability, NCP1216 drives large gate鈭抍harge MOSFETs, which
together with internal ramp compensation and built鈭抜n frequency
jittering, ease the design of modern AC鈭扗C adapters.
With an internal structure operating at different fixed frequencies,
the controller supplies itself from the high鈭抳oltage 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.
Current鈭抦ode control also provides an excellent input audio
susceptibility and inherent pulse鈭抌y鈭抪ulse control. Internal ramp
compensation easily prevents sub鈭抙armonic 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鈭抍alled
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 auto鈭抮ecovers.
