LNK623-626

LinkSwitch-CV Family

Energy-Efﬁcient, Off-line Switcher with Accurate

Primary-side Constant-Voltage (CV) Control

Product Highlights

Dramatically Simpliﬁes CV Converters

• Eliminates optocoupler and all secondary CV control circuitry

• Eliminates bias winding supply – IC is self biasing

Advanced Performance Features

• Compensates for external component temperature variations

• Very tight IC parameter tolerances using proprietary trimming

technology

• Continuous and/or discontinuous mode operation for design

ﬂexibility

Wide Range

HV DC Input

LinkSwitch-CV

• Frequency jittering greatly reduces EMI ﬁlter cost

• Even tighter output tolerances achievable with external resistor

selection/trimming

Advanced Protection/Safety Features

• Auto-restart protection reduces delivered power by >915 for

output short circuit and all control loop faults (open and shorted

components)

• Hysteretic thermal shutdown – automatic recovery reduces

power supply returns from the ﬁeld

• Meets HV creepage requirements between Drain and all other

pins, both on the PCB and at the package

(b) Output Characteristic

• No-load consumption <200 mW at 230 VAC and down to

below 70 mW with optional external bias

• Easily meets all global energy efﬁciency regulations with no

added components

*Optional with LNK623-624PG/DG. (see Key Application Considerations section for

clamp and other external circuit design considerations).

• ON/OFF control provides constant efﬁciency down to very light

loads – ideal for mandatory EISA and ENERGY STAR 2.0

regulations

• No primary or secondary current sense resistors – maximizes

efﬁciency

section for more information).

Description

The LinkSwitch-CV dramatically simpliﬁes low power, constant

voltage (CV) converter design through a revolutionary control

technique which eliminates the need for both an optocoupler and

secondary CV control circuitry while providing very tight output

voltage regulation. The combination of proprietary IC trimming

and E-Shield™ transformer construction techniques enables

Clampless™ designs with the LinkSwitch-CV LNK623/4.

3. Packages: P: DIP-8C, D: SO-8C.

LinkSwitch-CV provides excellent cross-regulation for multiple-

output ﬂyback applications such as DVDs and STBs. A 700 V

power MOSFET and ON/OFF control state machine, self-biasing,

frequency jittering, cycle-by-cycle current limit, and hysteretic

thermal shutdown circuitry are all incorporated onto one IC.
