    Lead-Acid Charger and LED Driver using TPS5402 (Rev. A)
    The TPS5402 device is a non-synchronous buck regulator with a wide operating range from 3.5 to 28 V.The switching frequency of the converters can be set from 50 kHz to 1.1 MHz with an external resistor.Frequency-spread spectrum operation is introduced for EMI reduction. TPS5402 supports pulse-skippingmode to enhance the efficiency at light load, making this device an ideal pick for applicati

    Designing Overcurrent protection for TPL7407L Peripheral Driver
    Microcontroller units (MCUs) are generally limited with lower drive on the I/Os. Most of the applicationsrequiring MCU boards to drive high-current loads need discrete implementation and additional components, which use a lot of board space. This board space is called a peripheral driver section. The TPL7407L device is an integrated peripheral driver with seven channel drivers inside. The TPL740
