EMD2055-00FK08NRR Description

Short technical summary and product information.

The ESMT EMD2055-00FK08NRR is a highly efficient, step-up DC/DC converter suitable for driving white LEDs in applications such as mobile phones, digital still cameras, and portable devices. It can drive up to 10 serially connected white LEDs from a single Li-Ion battery or multiple combinations with a DC power supply from 2.5V to 5.5V.

This converter utilizes current mode and pulse-width modulated (PWM) operation with a high switching frequency of 1.2MHz, enabling the use of small inductors and capacitors. Key features include over-voltage protection up to 36.5V, low quiescent current of 120 μA, and a shutdown current of less than 1μA. It also incorporates internal compensation and soft-start circuits.

The EMD2055 is available in a low-profile TDFN-8L (2x2mm) package, making it suitable for space-constrained designs. It supports PWM dimming control and includes various protection circuits like under-voltage lockout, current limit, and thermal shutdown for system safeguarding.

This device is ideal for applications requiring efficient LED driving and voltage boosting. Its compact package and integrated features simplify design and reduce component count.
