GreenChip™II SMPS control IC
FEATURES Distinctive features • Universal mains supply operation (70 to 276 V AC) • High level of integration, giving a very low external component count.
Green features • Valley or zero
voltage switching for minimum switching losses • Efficient quasi-resonant operation at high power levels • Frequency reduction at low power standby for improved system efficiency (3 W) • Cycle skipping mode at very low loads; Pi 300 mW at no-load operation for a typical adapter application • On-chip start-up current source • Stan...
