MAX8607 1MHz PWM Boost Converter for 1.5A White LED Camera Flash

Description

The MAX8607 white LED boost converter is optimized for camera flash/strobe applications using high-current white LEDs. The MAX8607 integrates a 1MHz PWM boost converter, 1.5A low-dropout (LDO) current regulator, and logic control circuitry for a space-saving LED flash design. Two logic inputs control four modes of operation: shutdown mode reduces the quiescent current to 0.1µA (typ), movie mode supplies up to 360mA of LED current for continuous lighting, flash mode supplies up to 1.5A of LED current for short-duration lighting during an exposure, and disco mode supplies +5V (at up to 1A) to external circuits while driving the LED with a fixed 80mA current.

The internal 1MHz boost converter features an adaptive control scheme with an internal switching MOSFET and synchronous rectifier to improve efficiency and minimize external component count. The MAX8607 is available in a 14-pin, 3mm x 3mm TDFN package (0.8mm max height).
