LV5044V
LV5044V is DC-DC Converter Controller manufactured by onsemi.
Ordering number : ENA0534
Bi-CMOS IC
2ch step-down circuit DC-DC Converter Controller http://onsemi.
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).
