The TPS65030 device contains three charge pumps and one LDO to generate all supply voltages necessary for a USB On-The-Go (OTG) implementation using TUSB6010. The charge pumps are optimized for a single Li-Ion cell input or for 5 V from the USB bus. The input voltage range is 3 V to 5 V for the battery voltage. High efficiency is achieved by using fractional conversion techniques for the charge pumps in combination with a power saving sleep mode. The current-controlled charge pumps ensure low input current ripple and low EMI. Small sized external ceramic capacitors are required to build a complete power-supply solution. To reduce board space to a minimum, the device switches at 1-MHz operating frequency and is available in a small 25-ball chip scale package (YZK).
