Energy saving offline high voltage converter

Datasheet - production data

Applications

 Low power SMPS for home appliances, home

automation, industrial, consumer, lighting

 Low power adapters

SSOP10

Description

The device is a high voltage converter smartly

integrating an 800 V avalanche-rugged power

MOSFET with PWM current mode control. The

Features

 800 V avalanche-rugged power MOSFET

allowing ultra wide VAC input range to be

covered

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.

 Embedded HV startup and sense-FET

 Current mode PWM controller

 Drain current limit protection

– 370 mA (VIPER113)

– 480 mA (VIPER114)

– 590 mA (VIPER115)

 Wide supply voltage range: 4.5 V to 30 V

 Minimized system input power consumption:

– Less than 10 mW at 230 V in no-load

Figure 1. Basic application schematic

condition

– Less than 400 mW at 230 V with 250

mW load

 Jittered switching frequency reduces the EMI

filter cost:

– 30 kHz ± 7% (type X)

– 60 kHz ± 7% (type L)

– 120kHz ± 7%(type H)

 Embedded E/A with 1.2 V reference

 Protections with automatic restart:

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

OVP, max. duty cycle counter, VCC clamp

 Pulse-skip protection to prevent flux- runaway

 Embedded thermal shutdown
