The MAX77387EWP+T is a high-efficiency LED driver IC designed for smartphone camera flash applications. It integrates a dual-phase 2A PWM DC-DC step-up converter and two programmable 1A high-side, low-dropout LED current regulators for flash and torch functions.
This device operates from an input supply voltage range of 2.5V to 5.5V, making it suitable for new battery technologies. The step-up converter features an internal switching MOSFET and synchronous rectifier for improved efficiency and reduced external component count. Dual-phase operation ensures low output ripple and a compact solution size. The high-current regulators can source up to 1A each in flash mode and up to 250mA each in torch mode, with the ability to combine them for up to 2A in flash mode.
The output voltage can be adaptively controlled, boosting only as high as necessary to support the required LED forward voltage. This adaptive mode reduces IC power dissipation by optimizing the boost ratio and minimizing losses in the current regulators. The IC supports both analog and PWM dimming control schemes and includes features like shorted LED detection, overvoltage, and thermal shutdown protection.
Packaged in a 20-WLP (20-UFBGA) format, the MAX77387EWP+T is designed for surface mount applications. Its operating temperature range is -40°C to 85°C (TA).
