NCP1910B100DWR2G数据手册规格书PDF详情

Housed in a SO−24WB package, the NCP1910 combines

a state-of-the-art circuitry aimed to powering next generation of ATX

or flat TVs converters. With a 65 or 100 kHz Continuous Conduction

Mode Power Factor Controller and a LLC controller hosting

a high-voltage driver, the NCP1910 is ready to power 85+ types of

offline power supplies. To satisfy stringent efficiency considerations,

the PFC circuit implements an adjustable frequency fold back to

reduce switching losses as the load is going light. To cope with all the

signal sequencing required by the ATX and flat TVs specifications, the

controller includes several dedicated pins enabling handshake

between the secondary and the primary sides. These signals include

a power-good line but also a control pin which turns the controller on

and off via an opto coupler. Safety-wise, a second OVP input offers the

necessary redundancy in case the main feedback network would drift

away. Finally, a fast fault input immediately reacts in presence of an

over current condition by triggering an auto-recovery soft-start sequence.

Features

• Fixed-Frequency 65 or 100 kHz CCM Power Factor Controller

• Average Current-Mode Control for Low Line Distortion
