Summit launches driver for Autofocus device

Summit Microelectronics has introduced the SMB274 programmable driver for the Lens Vector solid-state Autofocus device.

The SMB274 demonstrates mixed-signal power management, integrating high-performance analogue power and high-density digital control.

This high level of integration combined with micro-power operation in an ultra-compact CSP package and minimum external components yields a solution for the next generation of miniature digital cameras employing Lens Vector Autofocus technology.

Lens Vector has developed optical technology that can shape, steer and focus light without mechanical movement.

The company's technology addresses the need for autofocus and other advanced optical features in the market for miniature cameras embedded in mobile phones, laptops, pocket video camcorders and other consumer electronics.

Lens Vector's Autofocus aims to replace the autofocus mechanisms currently found in camera phones with an easy-to-integrate solid-state component.

The SMB274 combines all the features and functions required to support the LVAF device operation.

The Autofocus driver is powered by an on-chip charge pump, while integrated feedback signal processing optimises performance and minimises external components.

To ease system integration the SMB274's I2C/SMBus serial interface and non-volatile configuration options provide simple host control and flexibility to address various applications.

Together, these features enable operation with existing and emerging autofocus control systems in mobile-phone cameras.

The SMB274 is offered in a 1.34 x 2.34mm, 15-ball WLCSP package.
