The SMB118 is a highly integrated and flexible seven-channel power manager designed for use in a wide range of applications. It features digital programming of all major parameters, including output voltage setpoint/margining, sequencing and digital soft start, independent enable/disable outputs, input/output UV/OV voltage thresholds, PWM/PFM mode, and switching frequency. It also has six programmable regulator channels with 1.5% accuracy, a programmable linear Li-Ion battery charger, and other characteristics. The product is suitable for portable media players, digital camcorders/still cameras, smart PDA/camera phones, handheld GPS/PDAs, TFT-LCD displays/monitors/TVs, and more.
The Summit SMB118 is a highly integrated seven-channel power manager designed for portable applications such as digital camcorders, cameras, and mobile phones. It features digital programming of all major parameters via a PC interface and non-volatile memory, allowing system designers to tailor the device for specific multi-channel power supply needs.
The device integrates three synchronous step-down converters, one configurable step-up or step-down converter, one step-up converter, one linear regulator, and a programmable Li-ion battery charger. It supports an input range of +2.7V to +6.0V and includes built-in protection features like current limiting, UV/OV, and thermal protection.
