LM3550 Datasheet 5a Flash Led Driver

Manufacturer: National Semiconductor Corporation

Overview: LM3550 PRODUCT BRIEF .. May 1, 2009 LM3550 PRODUCT BRIEF 5A Flash LED Driver with Automatic Vf and ESR Detection for Mobile Camera.

General Description

LM3550 is a low noise, switched capacitor DC/DC converter designed to operate as a current-limited and adjustable (up to 5.3V) super-capacitor charger.

LM3550

Key Features

  • user selectable super-capacitor charge termination voltages and an optimal charge termination mode that maximizes flash energy efficiency by accounting for flash element losses. Additionally, the device provides one adjustable constant-current output (up to 200mA) and one NFET controller ideal for driving one or more high current LEDs either in a high power Flash mode or a low power Torch mode. The LM3550 can be configured to utilize a proprietary supercapacitor charging scheme (Optimal Mode), a.
