Vishay Intertechnology, Inc. Integrated Circuits (ICs) - Power Management (PMIC) - LED Drivers SIP12401DMP-T1-E3

The SIP12401DMP-T1-E3 is a boost controller integrated circuit designed for driving white LEDs in handheld devices, utilizing double AA cell or Li-Ion batteries. It operates within an input voltage range of 1.8 V to 5.0 V and features a fixed PWM switching frequency of 600 kHz, which enhances efficiency by providing uniform brightness across series-connected LEDs without the need for ballast resistors. The device allows for external adjustment of LED current for brightness control and includes integrated features such as undervoltage lockout (UVLO) and soft-start capabilities. This IC is packaged in a lead-free 6-pin PowerPAK MLP33 package and is rated for operation over an industrial temperature range of -40 ¬8C to 85 ¬8C. The shutdown current is notably low, at less than 1 ¬µA, making it suitable for battery-powered applications. The SIP12401DMP-T1-E3 is ideal for applications requiring efficient LED backlighting, such as in digital cameras and portable devices.
