Datasheet

Zero-power off-line high voltage converter

Features

•

Smart stand-by architecture using the zero-power mode (ZPM)

ZPM management by MCU easily realizable

800 V avalanche-rugged power MOSFET allowing ultra wide VAC input range to

be covered

SO16 narrow

•

Embedded HV startup and sense-FET

Current mode PWM controller

Drain current limit protection (OCP)

Wide supply voltage range: 4.5 V to 30 V

Self-supply option allows to remove the auxiliary winding or bias components

Minimized system input power consumption:

–

Less than 4 mW @ 230 V_ACin ZPM

Less than 10 mW @ 230 V_ACin no-load condition

Less than 400 mW @ 230 V_ACwith 250 mW load

•

Jittered switching frequency reduces the EMI filter cost

–

60 kHz ± 7% (type L)

120 kHz ± 7% (type H)

•

Embedded E/A with 1.2 V reference and separate ground for easy negative

voltage setting

Protections with automatic restart: overload/short circuit (OLP), max. duty cycle

counter, V_CCclamp

•

Pulse-skip protection to prevent flux-runaway

Embedded thermal shutdown

Built in soft start for improved system reliability

Applications

•

SMPS for home appliances, home automation, industrial, lighting and

consumers
