The SMB112 is a highly integrated and flexible five-channel power manager designed for powering TFT/LCD display panels and for driving low- and high-power white-LEDs. The built-in digital programmability allows system designers to custom tailor the device to suit almost any multi-channel power management application.

This document describes an application example of the SMB113 four-channel programmable DC-DC controller. It features digital programming and non-volatile memory for programming major parameters such as output voltage set point, input/battery voltage monitoring, output power-up/down sequencing, digital soft-start and output slew rate, output voltage margining, UV/OV monitoring of all outputs, and independent enable/disable outputs via the I2C interface. It also includes a user-friendly graphical user interface (GUI), four synchronous step-down output channels, an input range of +2.7V to +6.0V, highly accurate reference and output voltage, and low power mode.

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.

This datasheet provides detailed information on the SMB122 Nine-Channel Programmable DC-DC Power Manager with Battery Charger.

The SMB135 is a programmable single-cell lithium-ion/lithium-polymer battery charger for a variety of portable applications. The device provides a simple and efficient way to charge high-capacity Li-Ion batteries via a USB port or an AC adapter. Unlike conventional devices, the SMB135’s high-efficiency operation eliminates large internal temperature rise and localized hot spot in handheld devices.
