Brief Description
ZLED7001 Features
The ZLED7001, one of our ZLED family of LED control
ICs, is a peak current-mode control LED driver IC that is
optimal for buck LED driver applications. The ZLED7001
operates in constant off-time mode. Capable of
operating efficiently with voltage sources ranging from 8
VDC to 450 VDC or rectified 110 VAC/ 220 VAC, it is
ideal for High Brightness (HB) LED applications. The
ZLED7001 provides a PWM input for an external
dimming control signal. The ZLED7001’s linear dimming
input can be used both for linear dimming (0 to 240 mV)
and temperature compensation of the LED current.
• Wide input range from 8 VDC to 450 VDC or
110 VAC/220 VAC
• Temperature compensation to protect the LEDs and
extend LED lifetime
• Operates in constant off-time mode
• Both PWM and linear dimming control signal inputs
available
• Very few external components needed for operation
• Broad range of applications: outputs greater than 1A
Because the ZLED7001’s response time is limited only
by the rate of change in the inductor current, it attains a
high performance pulse-width modulation (PWM) dim-
ming response. The ZLED7001 ensures proper output
current regulation, without loop compensation, via peak
current-mode operation.
Application Examples
• Line-powered replacement LED lighting
• Illuminated LED signs and other displays
• LED street and traffic lighting
• Constant-current source for general purposes
• Architecture / building LED lighting
• LED backlighting
• Line powered LED flood lighting
• Interior / exterior LED lighting

Circuit Description
The ZLED7001 is a peak current-mode-control LED driver IC that operates in constant off-time mode, enabling
proper LED current control without additional loop compensation or high-side current sensing. The ZLED7001
supports both linear and PWM control of the LED current. Only a few external components are needed for typical
applications. It is well-suited for buck LED driver applications.

2.2. Application Signal Flow
A capacitor between the TOFF pin and ground determines the internal timer’s off-time. The timer pulses set flip-flop
in the ZLED7001, turning on the GATE pin driver, which is connected to the Q1 external MOSFET. When Q1
turns on, a ramp current flows through the LED(s), the L1 external inductor, and the external sense resistor RCS.
This results in a ramp voltage applied at the CS pin, which the ZLED7001’s two internal comparators continually
compare to the voltage at its LD pin and its internal 240mV reference. If either comparator goes high and the
blanking time is expired (see Table 1.3), the flip-flop is reset, causing the GATE pin output to go low, shutting off
the current through the LED(s).
The peak current control scheme with constant off-time can easily operate at duty cycles higher than 0.5 and also
gives inherent input voltage rejection, making the LED current almost insensitive to input voltage variations.

2.3. Input Voltage Regulator
The value and rating of the RIN input resistor must be selected as needed to drop the application supply voltage
(Vs) to the proper operating voltage for the ZLED7001 specified in section 0 (see equation (2) below). When these
conditions are met, the ZLED7001’s internal input voltage regulator maintains a stable 7.1V (typical) at the VIN pin
to power the ZLED7001. A low-equivalent-series-resistance (ESR) bypass capacitor is required on the VIN pin to
provide a low-impedance path for the GATE pin output driver’s high frequency current.
The VIN pin draws an input current that is the sum of the 0.5mA (typical) required by the internal circuit and the
average current drawn by the GATE driver. The GATE driver current is primarily determined by the GATE charge
(QG) and switching frequency (fs) of the external MOSFET as shown in equation (1).
IIN ≈ 0.5mA +

2.4. Current Sensing
Assuming a 30% current ripple in the inductor, the sense resistor RCS can be calculated as shown in equation (3):
VCSTH
RCS
=
(3)
1.15∗ILED
Where
VCSTH = 240mV (typical)
The current sense input of the ZLED7001 is connected to the non-inverting inputs of two comparators. The
inverting terminal of one comparator is tied to an internal 240mV reference and the inverting terminal of the other
comparator is connected to the LD pin. The outputs of both comparators are fed into an OR gate, and the output
of the OR gate is connected to the reset pin of the flip-flop. Thus, the comparator that has the lower voltage at the
inverting input determines when the GATE output is turned off.
The comparator outputs also include a typical 480ns blanking time that prevents spurious turn-offs of the external
MOSFET due to the turn-on spike normally present as a result of transistor gate-source capacitance. In rare
cases, this internal blanking time might not be enough to filter out the turn-on spike. If so, an external RC filter
must be added between the external sense resistor (RCS) and the CS pin.
Note that the comparators are relatively fast: 80ns typical response time. Invalid triggering by these comparators
could result if the layout fails to minimize external inductances.
2.5. Timing Circuit
The timing circuit in the ZLED7001 is controlled by a single capacitor connected from TOFF to ground.
T
OFF, the time of the cycle period, is given by equation (4):
COFF
(4)
TOFF _TIME = 510ns ∗ 1 +
10 pF
2.6. PWM Dimming Application Circuit
For PWM dimming applications, the ZLED7001’s PWMD pin is driven with a low-frequency square-wave control
signal. The GATE pin’s driver is enabled when the control signal is high and disabled when the control signal is
low. The LED current’s rise and fall rate is controlled only by the inductance value, the supply voltage, and LED
forward voltage.
If the PWMD pin is allowed to float, the PWM dimming function is disabled.
2.7. Linear Dimming Application Circuit
For linear dimming applications, an external voltage ranging from 50mV (typical) to 240mV (typical) is applied to
the LD (linear dimming) pin to control the LED current during operation. Linear dimming can be used to adjust the
LED current level to reduce the LED’s brightness. In this case, connect a resistor between the VREF pin and the
LD pin and connect a negative-temperature-coefficient (NTC) thermistor between the LD pin and ground. The
ZLED7001 can also provide temperature compensation, (see the application circuit on page 1 and section 2.8).

April 20, 2016
ZLED7001 Datasheet
A group of modules based on the ZLED7001 can be matched in LED brightness using the linear dimming input
with the PWM dimming feature still available for overall brightness control.
If the LD pin is not used, it must be connected to the PWMD pin, which is internally pulled-up. When the LD pin
voltage drops below 50mV, the GATE output is switched off.
2.8. Temperature Compensation
ZLED7001 provides thermal protection for the connected LEDs. Applying an NTC thermistor close to the LED
string will enable the temperature compensation of the LED current. Refer to the application circuit on page 1. If
the temperature of the LEDs rises, the resistance of the NTC thermistor decreases until the voltage of the LD pin
falls below 240mV. Then the average current is controlled by the LD pin and the temperature compensation
function starts. The upper threshold to start compensation is given by equation (5):
RNTC
(5)
VLDH =~ 240mV =VREF
∗
RNTC + R1
Considering the limit for IREF, under all conditions R1 must be selected larger than 2.2kΩ. Assuming a 30%
inductor current ripple, the temperature compensated continuous current can be computed as shown in
equation (6):
VREF
RNTC
(6)
∗
IOUT
=
1.15 ∗ RS
RNTC + R1
When the LD pin voltage drops below 50mV (typical), the GATE output is switched off. The transition to dimming
as well as the switch-off is reversible as soon as the respective thresholds are exceeded after the LED assembly
cools. Adding a capacitor C1 from the LD pin to ground will reduce noise on the LD input.
2.9. Design Example
A common application for an AC-line-powered ZLED7001 is luminants with a string of several LEDs operated by
one driver. For the example, the following constraints are assumed:
Application:
15W LED luminant with 13 HB LEDs in 1 string
VINAC = 230 VAC
AC supply voltage:
Average DC supply voltage:
VINDC ≈ 280 VDC resulting after bridge rectification and filtering with a 10μF
capacitor; power factor correction is not considered.
LED string forward voltage:
LED string average current:
ΣVF = 13*3.3V ≈ 43V
ILED = 350mA
IC Input Resistor (RIN) and Hold Capacitor (CIN):
For a given 2N60 MOSFET and a maximum expected switching frequency of 100kHz, the IC input current will be

An 180kΩ type can be chosen with a power rating of ≥0.5W. CIN is chosen to be a 10μF/ ≥10V capacitor.
TOFF Time Capacitor (COFF

The selection of the operation frequency is based on a tradeoff between higher frequencies allowing for smaller
and less expensive inductors and lower frequencies incurring lower losses in the power switch.
An estimation of the duty cycle D is based on the ratio of output voltage over input voltage:

IRipple
Lower ripple at the same average current will increase the lifetime of the LEDs but requires a more expensive
higher value inductor and increased thermal losses since the inductor’s DC resistance will increase as well. The
DC resistance of the inductor is an important design parameter, too. A capacitor placed in parallel with the array
of LEDs can be used to reduce the LED current ripple while keeping the same average current.
The inductor chosen must have a saturation current higher than the peak output current and a continuous current
rating above the required mean output current. The circuit design must also consider the decrease of inductance
and saturation current with rising temperature.
Current Sense Resistor (RCS)
With peak current-mode control, the output is switched off when the LED current reaches its maximum value
summing up the average LED current and half of the defined current ripple, yielding for the given example

MOSFET (Q1) and Diode (D1)
The MOSFET and diode must be dimensioned with a minimum 50% safety rating of their relevant voltage and
current parameters. Thus a FET with minimum 500V drain-source breakdown voltage and 0.6A drain current as
well as a fast recovery diode with at least 500V reverse voltage and a 0.6A forward current may be selected.
