CY8CLEDAC02

AC-DC Controller for Dimmable

LED Lighting

Features

Description

■ AC offline input range from 80 to 277 VAC

■ Up to 25 W output power range

The CY8CLEDAC02 is a high performance offline LED driver,

designed to interface directly with most conventional phase cut

based wall dimmers. The device uses proprietary digital control

technology to provide automatic detection of dimmer type

(leading or trailing edge). It automatically generates dimming

signals for LED loads and has the ability to dim down to 2

percent. It modulates LED brightness using a linear dimming

scheme and switches to a pulse width modulation (PWM) based

dimming scheme for output current levels lower than 20 percent

of the full load current. In PWM mode optimized dimming

frequencies in the range of 900 Hz result in zero visible flicker.

■ Intelligent wall dimmer detection:

❐ Leading edge (R, RL) dimmers

❐ Trailing edge (RC, RLC) dimmers

❐ No dimmer

■ Wide dimming range from 2 to 100 percent

■ Resonant control to achieve high efficiency

(85 percent without dimmer)

At the heart of a CY8CLEDAC02 based system is the chopping

circuit which provides the load necessary to enable correct wall

dimmer operation. It also improves PF when there is no dimmer

on the line.

■ Meets harmonic requirement with high power factor

(0.7 without dimmer)

■ Primary-side sensing eliminates opto-isolators

■ Tight LED current regulation (typically < + 2.5 percent)

■ Low startup current (typically 10A)

The devices’ proprietary primary side sensing enables tight LED

current regulation and eliminates the need for secondary

feedback circuitry. No opto-couplers are necessary to meet UL

isolation requirements; enabling flyback conversion with

automatic isolation.

■ Low startup time (typically 0.5 s with active startup)

The CY8CLEDAC02 operates in quasi-resonant mode to

achieve high efficiency. This mode of operation helps minimize

external component count and simplifies EMI design, lowering

the total bill of material cost.

■ Multiple protection features:

❐ Output overvoltage protection (OOVP)

❐ Output short circuit protection (OSCP)

❐ Overtemperature protection (OTP)

❐ Current-sense resistor short protection (CSSP)

❐ Peak current limit protection (PCLP)

❐ Single-point fault protection

The device’s cycle-by-cycle adaptive digital regulation uses

critical discontinuous conduction mode (CDCM) when driving

LED loads. The control algorithm for cycle-by-cycle regulation

has internal compensation for guaranteed system phase and

gain margins; requiring no external components for loop

compensation.

■ Applications:

❐ Dimmable offline LED driver

❐ Dimmable LED replacement lamps

❐ Dimmable LED luminaires

The CY8CLEDAC02 has full featured circuit protection not

normally available with other primary-side control solutions. The

built-in protection includes output overvoltage protection, output

short

circuit

protection,

overtemperature

protection,

current-sense resistor short protection, and peak current limit

protection. It also enables automatic LED brightness adjustment

to compensate for temperature drift by simply connecting a NTC

resistor to the V_Tpin.
