APPLICATION INFORMATION
APPLICATION OVERVIEW
Most of today
’s battery-powered portable electronics allow and/or require data transfer with a PC. One of the
fastest data transfer protocols is via USB On the Go (OTG). As Figure 20 shows, the USB OTG circuitry in the
portable device requires a 5-V power rail and up to 140mA of current. The TPS60150 may be utilized to provide
a 5-V power rail in a battery powered system.
Alternatively, low-cost portable electronics with small LCD displays require a low-cost solution for providing the
WLED backlight. As shown in Figure 21, the TPS60150 can also be used to drive several WLEDs in parallel, with
the help of ballast resistors.

BASIC OPERATION PRINCIPLE
The TPS60150, regulated charge pump, provides a regulated output voltage for various input voltages. The
TPS60150 regulates the voltage across the flying capacitor to 2.5V and controls the voltage drop of Q1 and Q2
while a conversion clock with 50% duty cycle drives the FETs.
