Brief Description
Benefits
The ZLED7022, one of our ZLED family of LED control
ICs, is a low-noise, constant-frequency charge pump
DC/DC converter that can drive up to six LED channels,
providing a programmable constant current level ranging
from 1.8mA to 20mA per LED channel. It can also drive
higher current LEDs because its current sinks can
operate in parallel. It enables white or other color LED
applications that require uniform intensity and/or linear
progressions in brightness. Capable of operating effi-
ciently with DC voltage supplies ranging from 2.8V to
5.5V, it is ideal for small, battery-powered applications
because very few external components are needed:
typically one small-dimension 1μF capacitor across the
C+ and C- pins and two small-dimension 2.2μF capaci-
tors to GND from the VCC and Vout pins.
• Current matching accuracy: ±0.9% (typical)
• One-pin on/off or brightness control for up to six
LEDs via a simple PCC serial interface—no pulse-
width modulation or additional control circuit needed
• 14 programmable current levels for achieving real-
time control of effects such as LED fade-out or
sudden changes in brightness
• Low EMI and back-injected noise because the
charge pump is not inductor-based
• Very few external components needed for operation
• Flexible design enables diverse LED applications: up
to 20mA per channel
• LED driver family concept with low-voltage
four-channel LED driver ZLED7012
The ZLED7022’s Pulse Count Control (PCC) serial digi-
tal input is used to enable/disable the LEDs and set the
current level (14 settings using a nearly logarithmic
scale to provide a linear brightness progression). This
simple, high-speed interface allows efficient real-time
management of LEDs via microcontrollers or control
systems.

2.2. ZLED7022 Overview
The ZLED7022 is a low-noise, constant-frequency charge pump DC/DC converter for driving up to six LEDs with constant current
at a level controlled via a PCC serial digital interface, providing a uniform and linear brightness progression. Its 20mA (maximum)
current output per LED channel is optimal for low-voltage or battery-powered applications, such as portable applications powered
by 1-cell lithium batteries. The ZLED7022’s current sinks can operate in parallel for driving higher current LEDs. Only a few, small
external components are needed for typical applications. The ZLED7022’s charge pump operates at a fixed frequency (1MHz
typical) with minimal noise and harmonics.

April 20, 2016
ZLED7022 Datasheet
The current sinks [D5:D0] are controlled by the PCC serial data input on the EN/SET pin. Data is written to an internal data register
that sets the outputs to one of 14 current levels. The Vout pin provides a shared supply voltage for the LEDs. The capacitor across
the C+ and C- pins is the “pump capacitor” used by the charge pump.
2.3. ZLED7022 Soft-Start Feature
The soft-start feature protects against excessive inrush currents during the start-up of the charge pump circuit. This prevents
potential transient noise effects that can affect initial performance, especially in battery-operated applications toward the end of the
battery life.
2.4. ZLED7022 Low-Current Shutdown Mode
The ZLED7022 enters a low-current shutdown mode whenever its EN/SET input is held low longer than TOFF (500μs minimum). In
the low-current shutdown mode, the ZLED7022 draws minimal current (ISHDN=1μA typical, 2μA maximum) and the internal data
register that controls output current is reset to 0, which disables the outputs.
2.5. LED Current Control
The ZLED7022’s Pulse Count Control (PCC) serial digital interface is used to enable/disable the LED outputs and set the constant
current level to one of 14 settings using a nearly logarithmic scale (approximately 1.5dB difference between settings) to provide a
linear brightness progression as the current level increases/decreases. See Table 2.1 for the current level settings.
Because [D5:D0] are independent constant current sinks, the voltage at the LED output being driven is determined by the LED’s
forward voltage (VF). This enables accurate LED brightness control and matching by the control system.

2.6. PCC Serial Digital Interface
The ZLED7022 detects the rising edges of the control signal input on the EN/SET pin via an internal counter and decodes the
signal into one of the 14 current level settings given in Table 2.1. The control signal timing can vary (even during a programming
cycle), and its frequency can range from high data rates (e.g., 1MHz) to very low rates (e.g., 15kHz). (Also see section 2.4.) After
sending the constant current level code data, the control system holds the EN/SET signal high for time TLAT (500μs minimum) so
that the ZLED7022 latches the programmed current level code into the data register and the current level becomes active as
illustrated in Figure 2.1. The internal counter is then reset to zero to be ready for the next programming cycle. This process is
repeated for the next data sent by the control system for subsequent current level programming. See section 2.4 regarding the
low-current shutdown mode, which is entered when the EN/SET signal remains low for longer than TOFF (500μs minimum).

Operating Conditions
3.1. RF Noise Reduction
The ZLED7022 charge pump operates at a fixed frequency of 1MHz (typical) to limit noise and harmonics and prevent generation
of RF interference by the ZLED7022, which could affect operation of local communication devices, such as cell phones. The soft-
start feature also prevents noise transients caused by inrush currents due to charge pump start-up.
The ZLED7022 has significantly lower back-injected noise at the input pin of the charge pump (typically 60mV peak-to-peak),
compared to inductor-based DC/DC boost converter solutions for white LED backlight applications (typically 10 times higher).
3.2. ZLED7022 Thermal Protection
The ZLED7022 includes an on-board temperature sensing circuit that shuts down the ZLED7022 and turns off its outputs if the die
junction temperature exceeds 160°C (typical).

Application Circuit Design
4.1. Applications
The ZLED7022 is designed for white or other color LED applications requiring a controlled LED current that is generated from a
varying input voltage. Typical applications include main/sub LCD display backlighting, cell phones (including smartphones),
personal digital assistants (PDAs), MP3/MP4 devices, portable media players (PMPs), and general purpose low-voltage industrial
applications. See section 4.2.3 for details and requirements for the LEDs.

4.2. External Components
4.2.1.
External Capacitors Cout and Cin
The values and type of capacitors used for Cin and Cout can affect several circuit parameters including transient performance,
turn-on time, and output ripple. Use low equivalent series resistance (ESR) ceramic capacitors (internal resistance < 100mΩ) for
best performance, lower costs, and component size reduction. Low ESR capacitors can enable applications at the highest LED
forward voltage with the lowest supply voltage. Tantalum and aluminum electrolytic are not generally recommended because the
ESR is typically in the range of several ohms.
Note: The recommended starting value when determining the optimal value for Cout is 2.2μF. There is often a design trade-off
between low ESR ratings and smaller size because physically larger ceramic capacitors usually have a relatively lower ESR, which
can improve the operating range of the circuit.
Cin is a bypass capacitor (≥ 2.2μF) essential to proper operation because it must deliver the dynamic current for the charge pump.
4.2.2.
External Pump Capacitor
The external pump capacitor Cpump connected between the C+ and C- pins is an essential part of the ZLED7022’s internal charge
pump circuit. Because the ZLED7022 operates at a constant charge-pump frequency of 1MHz (typical), it is important that the
pump capacitance is greater than 0.47μF so it can transfer enough charge each cycle to supply sufficient load current. To reduce
voltage fluctuations on the supply line, do not use a value for the pump capacitor that is greater than the bypass capacitor, Cin.
© 2016 Integrated Device Technology, Inc.
11
April 20, 2016
ZLED7022 Datasheet
Select a pump capacitor value in the range of 0.47µF to 2.2µF depending on output current requirements; 1µF is recommended for
most applications. When designing the circuit to operate at high levels of output current, choose a higher value of capacitance; low
output currents do not require a large pump capacitor. As with Cin and Cout, low ESR ceramic capacitors are recommended for
the pump capacitor. See section 4.2.1 for a discussion of low ESR capacitors.
4.2.3.
LEDs
The ZLED7022’s low dropout current sinks are capable of driving most types of LEDs with forward voltages as high as 4.7V at full
current with a Vcc input supply of 2.8V to 5.5V. High-current LEDs can be driven by using any of the D5:D0 pins in parallel.
The brightness of the LEDs being driven will match despite any variations in the forward voltage (VF) of the individual LEDs
because the [D5:D0] output current sinks are matched with negligible voltage dependence (see section 1.3 for specifications).
4.3. Unused LED Driver Pins
LED driver pin D0 must always be used. If any of the LED driver pins [D1:D5] are unused, disable the pin(s) by connecting them to
ground to avoid noise coupling.
5
ESD Protection
From each I/O or VCC pin to GND, there is an ESD protection of ≥±3000V. Between the I/O pins, there is an ESD protection of
≥±1000V according the Human Body Model (HBM). The ESD test follows the Human Body Model with 1.5 kΩ/100 pF based on
MIL 883-G, Method 3015.7.
