STEVAL-ISA178V1 Datasheet, PDF (1/4 Pages) STMicroelectronics – RoHS compliant

STEVAL-ISA178V1
5 V / 200 mA high voltage buck-converter based on VIPer01
Data brief
Features
 Five-star energy efficiency for operation
under no load (PIN_no_load < 20 mW @ 230
VAC)
 Meets ErP Lot 6 Tier 2 requirements for
household and office equipment
 Compliant with the 10% load efficiency and
4-point average active-mode efficiency
targets prescribed by the European CoC ver.
5 Tier 2
 Meets IEC55022 Class B conducted EMI
even with reduced EMI filter, thanks to the
frequency jittering feature
 VIPer01 800V avalanche rugged technology
and embedded protections ensure enhanced
system reliability
 RoHS compliant
Applications

 Automatic restart protections: OLP, short
circuit, VCC clamp, max duty cycle counter,
thermal shutdown
 Pulse-skip protection to prevent the flux-
runaway
 Dimensions: 29 mm x 30 mm
Description
STEVAL-ISA178V1 is a compact and efficient
solution for AC-DC power supplies, and performs
voltage conversion from the main line down to 5
V output voltage.
The low current consumption of the VIPer01 and
its low VCC voltage allows extremely low input
power consumption under no load and light load
conditions.
The pulse skip feature embedded in our IC
reduces the peak current typically present during
the startup phase of a buck converter.
