产品概述 返回TOP 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 IQ) 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. 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. CXSD62333 is available in the Green TDFN-2×3-8L package. It is rated over the -40℃ to +85℃ temperature range. 产品特点 返回TOP • High Efficiency Up to 95% 应用范围 返回TOP Single Li-ion Battery-Powered Equipment 技术规格书(产品PDF) 返回TOP 需要详细的PDF规格书请扫一扫微信联系我们,还可以获得免费样品以及技术支持!
