LNK64x4-64x8

LinkSwitch-3 Family

Energy-Efﬁcient, Accurate Primary-Side Regulation

CV/CC Switcher for Adapters and Chargers

Product Highlights

Output

Dramatically Simpliﬁes CV/CC Converters

• Eliminates optocoupler and all secondary CV/CC control circuitry

• Eliminates all control loop compensation circuitry

Advanced Performance Features

ꢀide Range

High-ꢁoltage

DC Input

• Compensates for transformer inductance tolerances

• Compensates for input line voltage variations

• Compensates for cable voltage drop

• Compensates for external component temperature variations

• Very accurate IC parameter tolerances using test trimming technology

• Frequency jittering greatly reduces EMI ﬁlter cost

• Programmable switching frequency up to 85 kHz to reduce trans-

former size

LinkSwitch-3

Pꢀ-6907-020515

• Minimum operation frequency ﬁxed to improve transient load

response

Figure 1. Typical Application – Not a Simpliﬁed Circuit.

Advanced Protection/Safety Features

• Auto-restart protection reduces power delivered by >90% for output

short-circuit and control loop faults (open and shorted components)

• Hysteretic thermal shutdown – automatic recovery reduces power

supply returns from the ﬁeld

• Meets high-voltage creepage requirements between DRAIN and all

other pins both on the PCB and at the package

EcoSmart™– Energy Efﬁcient

• Easily meets all global energy efﬁciency regulations with no added

components

• No-load consumption at 230 VAC input with bias winding <10 mW for

LNK64x4-LNK64x6 and <30 mW for LNK64x7-LNK64x8

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

– ideal for CEC regulations

The LinkSwitch™-3 family of ICs dramatically simpliﬁes low power CV/

CC charger designs by eliminating an optocoupler and secondary

control circuitry. The device introduces a revolutionary control

technique to provide very accurate output voltage and current

regulation, compen-sating for transformer and internal parameter

tolerances along with input voltage variations.

LNK6428E / LNK6448E

Table 1. Output Power Table.

Notes:

1. Assumes minimum input DC voltage >90 VDC, K_P≥1 (Recommend K_P≥1.15

for accurate CC regulation), η >78%, D_MAX<55%.

2. Output power capability is reduced if a lower input voltage is used.

3. Minimum continuous power with adequate heat sink measured at 50 °C

ambient with device junction below 110 °C.

4. Assumes bias winding is used to supply BYPASS pin.

5. Package: D: SO-8C, E: eSIP-7C, K: eSOP-12B.

The device incorporates a 725 V power MOSFET, a novel ON/OFF control

state machine, a high-voltage switched current source for self biasing,

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

shutdown circuitry onto a monolithic IC.
