Energy saving off-line high voltage converter

Datasheet - production data



Jittered switching frequency reduces the

EMI filter cost:



30 kHz ± 7% (type X)

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, max. duty cycle counter, V_CCclamp

Pulse-skip protection to prevent

flux-runaway

Figure 1: Basic application schematic



Embedded thermal shutdown

Built-in soft-start for improved system

reliability

Applications



Low power SMPS for home appliances,

building and home control, small industrial,

consumers, lighting, motion control

Low power adapters



Description

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.

Features



800 V avalanche-rugged power MOSFET

allowing ultra wide V_ACinput 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 @ 230 V_ACin no-load

condition



Less than 400 mW @ 230 V_ACwith

250 mW load
