AL1697

HIGH PF, OFFLINE DIMMABLE LED DRIVER

WITH INTERNAL HIGH-VOLTAGE MOSFET

Description

Pin Assignments

The AL1697 is a high performance, high power factor, high efficiency

and high precision buck-boost LED driver for mains dimmable LED

lamp applications. The AL1697 topology provides an accurate output

current over wide line and load regulation. The wide switching

frequency operates at boundary conduction mode (BCM) to ease

EMI/EMC design, and testing to meet the latest regulatory standards.

VCC

The AL1697 with built in MOSFET solution reduces the bill of material

(BOM) cost by eliminating the need of auxiliary winding and an

external high voltage MOSFET. The AL1697 has extensive protection

features to enhance system safety and reliability. The AL1697 starts

reducing output current when the driver’s temperature is higher than

the built-in thermal foldback protection trigger point.

COMP

GND

SO-7

The AL1697 applies to a wide range of dimmers including leading

edge and trailing edge dimmer. Some can achieve deep dimming

down to 1%. The AL1697 dimming curve is compliant with the NEMA

SSL6 standard.

Applications



Mains Dimmable LED Lamps

Offline LED Power Supply Driver

The AL1697 is available in SO-7 package, which provides an extra

pin spacing between the high voltage MOSFET’s drain and low

voltage pins to increase electricity isolation.

Features



Three Internal High-Voltage MOSFET Options:

R_DSON)2.8Ω(3A /400V), 4Ω(2A/600V) and 1.8Ω(4A /670V)

for Super-Junction



Tight Current Sense Tolerance : 3%

Low Startup Current: 130µA

Low Operation Current: 170µA (Switching Frequency at 4kHz)

Single Winding Inductor

Wide Range of Dimmer Compatibility

NEMA SSL6 Dimming Curve Compliant

Internal Protections

Under Voltage Lockout (UVLO)

Leading-Edge Blanking (LEB)

Cycle-by-cycle Over Current Protection (OCP)

Output Open/Short Protection (OVP/OSP)

Thermal Foldback Protection (TFP)

Over-Temperature Protection (OTP)



SO-7 Package

Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)

Halogen and Antimony Free. “Green” Device (Note 3)

Notes:

1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant.

2. See http://www.diodes.com/quality/lead_free.html for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green"

and Lead-free.

3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and

<1000ppm antimony compounds.
