LM3102TL-1/NOPB

The LM3102TL-1/NOPB, which belongs to the DC/DC Switching Regulators of the Power Management Integrated Circuit (PMIC) Voltage Regulators family, is a step-up DC/DC converter designed for use in low voltage applications, including battery-powered systems.

The LM3102TL-1/NOPB offers a cost-effective solution for applications including portable battery-powered equipment, such as PDAs, cellular phones, laptop computers, and other consumer applications. It is ideal for other applications requiring low quiescent current and high efficiency at low output currents, such as LED driver applications, which typically require an output voltage of 1.2V to 3.3V.

In addition, the LM3102TL-1/NOPB is also suitable for applications that need to provide an output voltage below the battery voltage, such as wireless local area networks (WLANS), which typically require an output voltage of 1.8V. In addition, it can be used to generate the negative supply needed to drive digital logic in mobile devices.

The LM3102TL-1/NOPB utilizes an active-clamp, fixed-frequency control architecture to provide multiple output voltage levels above the battery voltage level. This fixed-frequency control architecture uses an internal voltage-controlled oscillator (VCO) to modulate the duty cycle of an internal driver circuit. This converter switches the current in an external MOSFET at a frequency of up to 500kHz.

The active-clamp control topology eliminates the need for a bias winding, allowing the use of a low-cost, low-profile inductor providing higher efficiency and output voltage accuracy. Additionally, the control parameters are externally adjustable and the components selection can be changed to meet different design requirements.

The LM3102TL-1/NOPB is an ideal solution for battery-powered or low-output-current applications requiring up to 500kHz frequency of operation. This device includes advanced features such as an active-clamp control topology and multiple output voltage levels above the battery voltage meaning it can easily be used to create a complete power solution.
