XX1188
10-Channel Power Management
Units for 3G Applications
DESCRIPTION
The XX1188 power-management IC (PMIC) is an complete,
efficient, compact devices suitable for 3G cellular
applications such as wireless data cards, handsets and
PDAs,. It integrates a 2MHz synchronous buck regulator,
nine low-dropout linear regulators (LDOs), a RESET
generator, and an 32KHZ crystal driver and buffer.
XX1188 is housed in a thin QFN4x4-28pin package.
