Company proprietary – Sales network use only Know–how ZXLD1615/1601 boost converter for LCD-OLED bias and DC-DC supply Features • Internal 30V NMOS switch • True analog output voltage control • High efficiency: 80% typical • 2.5V to 5.5V supply range •...
Functional Description The ZXLD1615 and ZXLD1601 are PFM inductive DC-DC boost converters. They are particularly suited to provide bias voltages for LCD and OLED displays. Up to 28V can be generated from an input voltage between 2.5 and 5.5V. The switch is integrated on chip together with the peak current sense resistor.

3V nom inal Competition There are several competitive solutions available for LCD and OLED biasing. Zetex has chosen to make a SOT23-5 pin compatible version of the industry leading LT1615. This should enable an easy acceptance of the part and a high chance of being considered as an alternative source.
Potential customers to look for • LCD or OLED module manufacturers where a complete display system is provided to end users. (This is also an opportunity for the ZXLD1937 when backlighting is included in the module.) • Manufacturers of handheld equipment incorporating color LCD or OLEDs where bias is generated externally to the display module.
