LD7242 - Highly-Integrated 6-Channel DC/DC Power Management IC

Datasheet Summary

Description

The LD7242 is a high-efficiency complete solution for power supply of digital video cameras (DVCs).

With six internal MOSFET DC-DC converters, it provides a maximum efficiency of 95% and generates all the critical power suppliers in DV systems.

Features

  • internal compensation to minimize external component count. For the complete protection, the LD7242 provides over current protection, over/under voltage protection, and thermal shutdown protection. The LD7242 can operate in 1-cell lithium-ion (Li+) or dual-battery (2AA) designs. It is available in a compact 32-Pin, 4mm x 4 mm WQFN package. +Patented Features ‧ Supply Voltage Range：1.5V to 5.5V ‧ Integrated Power MOSFET Switch ‧ Synchronous Buck Converter -Up to 95% Efficiency -Up to 100% Duty C.

LD7242 3/5/2012 Highly-Integrated 6-Channel DC/DC Power Management IC REV：02 General Description The LD7242 is a high-efficiency complete solution for power supply of digital video cameras (DVCs). With six internal MOSFET DC-DC converters, it provides a maximum efficiency of 95% and generates all the critical power suppliers in DV systems. The LD7242 includes 6 channels of converter and 3 LDOs and Power-Good flag. See the description as below. 6 Channel DC/DC Converters: CH1 is a synchronous boost converter for motor control and HDMI. CH2 is a selectable synchronous buck/boost converter for DSC system I/O power. CH3 is a synchronous buck converter for DSP core or external memory. CH4 is a synchronous buck converter for DSP core or external memory.
