Designing with Acrich 2
Features
4W MR
• Directly connect to AC
power using a Acrich IC
• High power efficiency
• High power factor
• Low THD
• Long life time
• The simplest BOM
• Miniaturization
• Lead free product
• RoHS compliant
Introduction
Acrich2 is designed to connect directly
to AC source via 2wires with no AC/DC
converter which is essential for conventional
general lighting. As there is no need of
converter, Acrich2 can realize as close
life-time as original LED and make a better
use of a space in many applications.
4W Bulb
Also, Acrich2’s high power factor can show
best energy saving effect in many lighting
applications.

1. Driver Configurations
1.1 Description
Acrich IC has a direct-driving architecture that drives Acrich directly from AC supply, without
AC-DC conversions.
Acrich IC has 8 channels, and activations of these channels and their current flows are controlled
by its internal controller so that Acrich currents, power dissipation and power factor are regulated
within proper ranges.
Acrich IC integrates all peripheral components including bridge diodes and passive components,
providing a simple and effective solution for LED light applications.

2.5 Surge Protection Circuit
A metal oxide varistor (MOV) is often used to protect lighting systems from electrical surges
and ring-wave effects, and help manufacturers meet safety and performance standards. The MOV
prevents short-duration voltage impulse. Lightning tests (IEC 61000-4-5) and ring-wave
Tests (IEEE C.62.41) can be used for these real-life threat simulation in the lab.
A surge protection circuit (SPC) consists of two components (MOV & fusible resistor) and it is not
necessary for normal operation of the Acrich IC module.

2.6 Dimming Performance (TRIAC Dimmer)
Incandescent lamp replacement with LED lamps is recently growing by leaps and bounds.
One of the requirements for these LED lamps is compatibility with dimmers designed for
incandescent lamps. Incandescent lamp primarily utilize phase modulating dimming through
TRIAC switches to control the power sent to the bulb.
