     CXSD62333 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 I_Q) mode with typical 30μA quiescent current for highest light load efficiency to maximize battery life.

The CXSD62333 integrates a pair of low on-resistance P-Channel and N-Channel MOSFETs to maximize efficiency and minimize external component count.nvo嘉泰姆

The CXSD62333 offers a typical 215ms power-good (PG) timer when powered up. When shut down, CXSD62333 discharges the output capacitor. Other features include internal digital soft-start, enable for power sequence, over-current protection and thermal shutdown.nvo嘉泰姆

CXSD62333 is available in the Green TDFN-2×3-8L package. It is rated over the -40℃ to +85℃ temperature range.nvo嘉泰姆
