Panasonic DC DC Switching Controllers LV5044V-TLM-E

The LV5044V-TLM-E is a high-efficiency, dual-channel step-down DC-DC converter controller IC designed for synchronous rectification. It integrates multiple functions, making it suitable for various applications, including LCD-TVs, DVD recorders, and gaming devices. The device features an input under-voltage lockout (UVLO) circuit, overcurrent and overtemperature detection, as well as soft start and soft stop functions. It supports 180¬8 interleaved operation for enhanced performance in multi-phase configurations and allows for synchronous operation when multiple devices are used. The LV5044V operates with a supply voltage range of 4.5V to 16V and can handle peak output currents of ¬±1.0A. It includes output voltage monitoring with power good, overvoltage protection (OVP), and undervoltage protection (UVP) with timer latch functions. The IC is housed in a 30-SSOP package and is rated for operation in temperatures from -20¬8C to +85¬8C. Its comprehensive protection features and flexibility make it a viable option for engineers looking to implement efficient power management solutions in their designs.
