Data brief
reach very low standby consumption (< 50 mW at
265 V_ac), while in the latter the IC is supplied by
an internal current generator, thus eliminating the
cost of the transformer auxiliary winding.
• Protection features available include thermal
shutdown with hysteresis and delayed
overload protection.
Features
• Input voltage range V_IN: 90 V_RMS - 265 V_RMS
• Output voltage V_OUT: 16 V
• Max output current I_OUT: 0.28 A
• Precision of output regulation V_{OUT_LF}: ±5%
• High frequency output voltage ripple V_{OUT_HF}:
50 mV
• Max ambient operating temperature T_A: 60 °C
• RoHS compliant
Description
The STEVAL-ISA129V1 demonstration board is a
16 V - 280 mA application set in non isolated
flyback topology using the VIPer16, a new off-line
high voltage converter by STMicroelectronics.
The VIPer16 features an 800 V avalanche rugged
power section, PWM operation at 115 kHz with
frequency jittering for lower EMI, limiting current
with adjustable set point, on-board soft-start, and
safe auto-restart after a fault condition.
Moreover, the VIPer16 can work with or without
the auxiliary winding. In the former case, it can
