2.1.

Kit Description

Overview

The ZLED7012KIT-E1 Evaluation Kit provides a quick and easy method for evaluating the ZLED7012 within its

basic application circuit. An on-board generator demonstrates the ZLED7012’s Pulse Count Control (PCC) digital

brightness control feature. Reading the

ZLED7012 Data Sheet

before using the Evaluation Kit is recommended

for understanding the operation of the ZLED7012 and the Evaluation Board.

The ZLED7012 is a low-noise, constant-frequency charge pump DC/DC converter that can drive up to four LED

channels, providing a programmable constant current level ranging from 1.8mA to 20mA per LED channel. The

ZLED7012’s current sinks can operate in parallel for driving higher current LEDs as well. The ZLED7012’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.

The Evaluation Board contains a standard 5-pin terminal connector to allow the user to easily interface with the

microcontroller and the ZLED7012 to evaluate its functions, features, and performance. The Evaluation Board

also has two push-buttons to send commands and change the operation mode of the ZLED7012.

Figure 2.1 shows the top view of the populated kit PCB.

2.2.

Power Supply

For easy operation with a 5V supply, the on-board female USB Mini-B connector K1 can be connected via the

enclosed cable to a USB A connector of a PC or USB power supply.

To operate the kit over the whole supply voltage range of 2.8V to 5.5V, an external power supply can be

connected to the Vdd and GND pins of the K2 header.

Since the product family members ZLED7012 and ZLED7022 use the same kit PCB differing only in the number

of current channels, the red power indicator LED D11 (for the ZLED7012KIT-E1 Evaluation Kit) or D12 (for the

ZLED7022KIT-E1 Evaluation Kit) will automatically point to the valid kit type when power is attached.
