    SGM6016

    1.2A, 1.6MHz, High Efficiency Synchronous Step-Down Converter
     
    1.2A, 1.6MHz, High Efficiency Synchronous Step-Down Converter
    GENERAL DESCRIPTION

    SGM6016 is a 1.2A, 1.6MHz step-down regulator, which is ideal for powering low-voltage microprocessors in compact devices such as GPS and cellular phones. It is optimized for generating low output voltages down to 0.8V. The supply voltage range is from 2.7V to 5.5V allowing the use of a single Li+ cell, three NiMH cells or a regulated 5V input. 1.6MHz pulse-width modulation (PWM) switching frequency allows using small external components. It has flexible operation mode selection of forced PWM mode and skip (low IQ) mode with typical 30μA quiescent current for highest light load efficiency to maximize battery life.

    The SGM6016 integrates a pair of low on-resistance P-Channel and N-Channel MOSFETs to maximize efficiency and minimize external component count.

    The SGM6016 offers a typical 215ms power-good (PG) timer when powered up. The timer output can be reset by RSI. When shut down, SGM6016 discharges the output capacitor. Other features include internal digital soft-start, enable for power sequence, over-current protection and thermal shutdown.

    SGM6016 is available in a Green TDFN-3×3-10L package. It is rated over the -40 to +85 temperature range.
