G5193R41D Description

Short technical summary and product information.

The G5193R41D from GMT is a full-featured 5.5V, 3A synchronous step-down current mode converter. It integrates two MOSFETs, enabling high efficiency at 3A loads. The device supports a switching frequency range from 300kHz to 2MHz, allowing for smaller inductor sizes and reduced component count.

Key electrical specifications include a typical 45mΩ MOSFET on-resistance, a ±1% voltage reference over temperature, and adjustable soft start. It operates with a typical supply current of 350µA and can enter a shutdown mode with a quiescent current of 2µA. The converter includes under-voltage lockout (UVLO) internally set at 2.6V and an open-drain power good output signal.

Designed for low-voltage, high-density power systems, the G5193R41D is suitable for point-of-load regulation for DSPs, FPGAs, ASICs, and microprocessors. It also finds applications in broadband, networking, and optical communication infrastructure.

The device is housed in a thermally enhanced 3mm x 3mm 16-pin QFN package, suitable for surface mounting. The operating temperature range is -40°C to +85°C.
