MAX17062 Evaluation Kit
Evluates:MAX17062
General Description
Features
o 90% Efficiency
The MAX17062 evaluation kit (EV kit) is a fully assem-
bled and tested surface-mount PCB that provides the
voltages required for active-matrix, thin-film transistor
(TFT), liquid-crystal displays (LCDs). The EV kit con-
tains a pulse-width-modulated (PWM) step-up switch-
ing regulator, a positive single-stage charge pump for
the TFT gate-on supply, and a negative single-stage
charge pump for the TFT gate-off supply.
o +2.6V to +5.5V Input Range
o Output Voltage Adjustable from VIN to 20V
o Output Voltages (+4.5V to +5.5V Input)
+15V Output at 600mA
+29V Output at 30mA (Positive Charge Pump)
-15V Output at 30mA (Negative Charge Pump)
The EV kit operates from a DC supply voltage of +4.5V
to +5.5V and is configured to operate with a switching
frequency of 1.2MHz. The step-up switching regulator
is configured for a +15V output and can provide 600mA
with a +4.5V input. The positive charge pump is config-
ured for a +29V output providing 30mA. The negative
charge pump is configured for a -15V output providing
30mA.
o 1.2MHz Switching Frequency (Selectable: 640kHz
or 1.2MHz)
o Programmable Soft-Start
o 0.01µA IC Shutdown Current (typ)
o Fully Assembled and Tested
The MAX17062 EV kit features low-quiescent current
and high-conversion efficiency (90%). The high switch-
ing frequency allows the use of small, surface-mount
components.
