MAX16814 Evaluation Kit
Evaluates:
MAX16814
General Description
The MAX16814 evaluation kit (EV kit) demonstrates
the MAX16814 high-brightness LED (HB LED) driver,
integrating a step-up DC-DC preregulator followed by 4
channels of linear current sinks. The step-up preregula-
tor switches at 350kHz and operates as a current-mode-
controlled regulator capable of providing up to 600mA
for the linear circuits. Each of the 4 linear channels can
operate up to 40V and provide up to 150mA per channel.
The 4 channels are configurable for 100mA or 150mA
HB LED output current. The IC is a 20-pin TSSOP pack-
age with an exposed pad for enhanced thermal power
dissipation.
The EV kit operates from a DC supply voltage of 6.5V
up to the HB LED string forward voltage. The EV kit can
withstand a 40V load-dump condition. The EV kit also
demonstrates the IC features such as adaptive voltage
optimization, undervoltage lockout (UVLO), overvoltage
protection (OVP), cycle-by-cycle current limit, thermal
shutdown, and digital PWM dimming operation using a
digital PWM input signal to control the brightness of the
HB LEDs. The EV kit also demonstrates a reference IC
design for automotive applications.
