DC-DC Converter Controller
Overview
The LV5044V is a high efficiency, 2-channel, step-down, DC-DC converter controller IC adopting a synchronous
rectifying system. Incorporating numerous functions on a single chip with easy external setting, it can be used for a
wide variety of applications. The device is optimal for use in multi-output power supply systems which are used in
LCD-TVs, DVD recorders, game machines, high-end office products, etc.
Features
? Provides dual step-down DC-DC converter controller circuits integrated on the same chip.
? Provides an input UVLO circuit, an overcurrent detection function, an overtemperature detection function, soft
start/soft stop functions, and a startup delay circuit.
? Output voltage monitoring functions (power good as well as OVP and UVP with timer latch functions)
? 180° interleaved operation between phase 1 and phase 2 (supports multiphase drive in 2-phase parallel operation
mode).
? Supports synchronous operation between different devices (supports master/slave operation when multiple devices
are used).
