1.2.2 MIC4802 Device Overview

The MIC4802 is a high efficiency White LED (WLED) linear driver designed to drive a
single LED up to 800 mA. The MIC4802 provides the highest possible efficiency, as this
architecture has no switching losses present in traditional charge pumps or inductive
boost circuits. It features a typical dropout of 280 mV at 800 mA. This allows the LEDs
to be driven directly from the voltage source eliminating switching noise/losses present
with the use of boost circuitry. The high accuracy (1% Typical) current regulated WLED
channel ensures uniform display illumination under all conditions. The brightness is
controlled through an Ultra Fast PWM Control interface operating down to less than 1%
duty cycle.

The 3.0V to 5.5V input voltage range of MIC4802 allows direct operation from one cell
Li-Ion as 3 to 4 cell Ni-Cd, Ni-MH or Alkaline batteries. Maximum battery life is assured
with a low 0.01 μA typical shutdown current.

Chapter 2. Installation and Operation

2.1 INTRODUCTION

MIC4802 is a high efficiency linear White LED driver designed to drive a single LED up
to 800 mA.

MIC4802 is a constant current driver designed to drive high power LEDs in various
lighting applications. The MIC4802 provides the highest possible efficiency as this
architecture has no switching losses present in traditional charge pumps or inductive
boost circuits. It features a typical dropout of 280 mV at 800 mA load. This allows the
LEDs to be driven directly from the voltage supply without the switching noise that is
present for switching solutions.

The MIC4802 Evaluation Board can be powered from 3.0V to 5.5V range and the LED
current is fixed at 600 mA through resistor R4.

An external high power LED can be connected between V
cathode) terminals in order to evaluate the MIC4802 at maximum performance
(800 mA). To do so, it is necessary to remove the Evaluation Board LED and modify
the R4 from 8.2 kΩ (600 mA) to 6.19 kΩ (800 mA).

To power up the MIC4802 Evaluation Board, the following steps must be completed:

1. Connect an external supply between V
polarity.

2. With the output of the power supply disabled, set its voltage to the desired input
test voltage (3.0V ≤ V
supply and the V
terminal, as the ammeter and/or power lead resistance can reduce the voltage
supplied to the device.

3. Connect a voltmeter between D1 and V
voltage.

The MIC4802 Evaluation Board has a pull-up resistor to V
voltage will be enabled when the input supply of >3.0V is applied. To disable the device,
apply a voltage of 1.2V to V
terminal (JP1).

The MIC4802 has a programmable LED current which is dependent by the R
The R

pin is used to set the peak current of the linear driver by connecting a R

SET

SET

value.

SET

resistor to ground. The theoretical average LED current can be estimated by applying
Equation 2-1.

EQUATION 2-1:

‘D’ is the duty cycle of the LED current during PWM dimming. When the device is fully
ON, the duty cycle equals 100% (D = 1).

2.2.2 Enable/PWM Feature (JP1)

The EN pin is equivalent to the enable pin for the linear drivers on the MI4802. It can
also be used for dimming by applying a PWM signal, as shown in the following scope
shots. Pulling the EN low for more than 40 ms puts the MIC4802 into a low IQ sleep
mode. The EN pin cannot be left floating because a floating enable pin may cause an
indeterminate state on the outputs. The first pulse on the EN pin must be equal or
greater than 60 μs to wake the part up in a known state. This equals to an 8.3 kHz PWM
signal at equal or greater than 50% duty cycle. Higher PWM frequencies may be used,
but the first pulse must be equal or greater than 60 μs.

2.2.3 D1 – LED Cathode (J6)

The D1 pins are the linear inputs for the LED. The anode of the LED is connected to
V

potential and the LED cathode is connected to the D1 pins. All the D1 pins must be

IN

connected together. The D1 voltage at dropout is the minimum voltage required by the
linear driver in order for the LED to be fully biased.

2.2.4 Output Noise and Ripple Measurements

To properly measure voltage ripple on either the input or output of any regulator, a
proper ring-in tip measurement is required. Standard oscilloscope probes come with a
grounding clip, or a long wire with an alligator clip. Unfortunately, for high-frequency
measurements, this ground clip can pick up high frequency noise and erroneously
inject it into the measured output ripple.

2.2.5 Board Layout Considerations

It is recommended that a copper plane is placed immediately under the MIC4802 and
it must be connected to the GND copper plane using a via under the device. As the
MIC4802 has an exposed pad, the copper plane will help conduct the heat away from
the device and improve thermal performance. Moreover, doing this will also help shield
the device and improve output ripple performance.
