The IS-CHPMP is a DC/DC voltage step-up converter with an input of 2.7-5.5V and an output of 16V for use in
driving OLED displays. The IS-CHPMP utilizes Maxim’s MAX8574 step-up converter to take advantage of its
floating output during shutdown mode. A 2x4 .100” header is required to interface with charge pump.
The IS-CHPMPHP is a DC/DC voltage step-up converter with an input of 2.7-5.5V and an output of 15V for
use in driving OLED displays. The IS-CHPMPHP utilizes LM2735YMF/NOPB step-up converter to take
advantage of its floating output during shutdown mode. A 2x4 .100” header is required to interface with charge
pump.
IS-CHPMP and IS-CHPMPHP are RoHS compliant.

4. Multi-Switch Operation
OLED power consumption is based on the number of pixels on. The safe way to calculate the number of OLED
products that can be powered by one charge pump is as stated below:
Number of OLED products =Charge Pump Current Capability
AllPixelsOn Mode Max Current
It is possible to have more OLED products powered by one charge pump since under normal operation not all
the pixels are on at the same time.
If more OLED product need to be powered, then multiple charge pumps can be placed in parallel.
