Energy saving off-line high voltage converter

Datasheet - production data

Applications

 Low power SMPS for home appliances,

building and home control, small industrial,

consumers, lighting, motion control

 Low power adapters

SSOP10

Description

Features

The device is a high voltage converter smartly

integrating an 800 V avalanche-rugged power

MOSFET with PWM current mode control. The

power MOSFET with 800 V breakdown voltage

allows the extended input voltage range to be

applied, as well as the size of the DRAIN snubber

circuit to be reduced. This IC meets the most

stringent energy-saving standards as it has very

low consumption and operates in pulse frequency

modulation under light load. The design of

flyback, buck and buck boost converters is

supported. The integrated HV startup, sense-

FET, error amplifier and oscillator with jitter allow

a complete application to be designed with the

minimum number of components.

 800 V avalanche-rugged power MOSFET

allowing ultra wide V input range to be

covered

 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 the auxiliary winding

or bias components to be removed

 Minimized system input power consumption:

– Less than 10 mW at 230 V in no-load

condition

– Less than 400 mW at 230 V with 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

 Protections with automatic restart:

overload/short-circuit (OLP), line or output

OVP, V clamp

 Pulse-skip protection to prevent flux-runaway

 Embedded thermal shutdown

 Built-in soft-start for improved system reliability
