SC121ULTRT规格书详情
Description
The SC121 is a high efficiency, low noise, synchronous step-up DC-DC converter that provides boosted voltage levels in low-voltage handheld applications. The wide input voltage range allows use in systems with single NiMH or alkaline battery cells as well as in systems with higher voltage battery supplies. It features an internal 1.2A switch and synchronous rectifi er to achieve up to 94 efficiency and to eliminate the need for an external Schottky diode. The output voltage can be set to 3.3V with internal feedback, or to any voltage within the specified range using a standard resistor divider.
Features
■ Input voltage — 0.7V to 4.5V
■ Minimum start-up voltage — 0.85V
■ Output voltage — fixed at 3.3V; adjustable from 1.8V to 5.0V
■ Peak input current limit — 1.2A
■ Output current at 3.3 VOUT — 80mA with VIN = 1.0V, 190mA with VIN = 1.5V
■ Forced PWM operation at all loads
■ Efficiency up to 94
■ Internal synchronous rectifier
■ No forward conduction path during shutdown
■ Switching frequency — 1.2MHz
■ Soft-start startup current limiting
■ Shutdown current — 0.1μA (typ)
■ Ultra-thin 1.5 × 2.0 × 0.6 (mm) MLPD-UT-6 package
■ Lead-free and halogen-free
■ WEEE and RoHS compliant
Applications
■ MP3 players
■ Smart phones and cellular phones
■ Palmtop computers and handheld instruments
■ PCMCIA cards and memory cards
■ Digital cordless phones
■ Personal medical products
■ Wireless VoIP phones
■ Small motors
SC121ULTRT属于集成电路(IC) > 稳压器 - DC-DC 开关稳压器。Semtech Corporation制造生产的SC121ULTRT稳压器 - DC-DC 开关稳压器DC-DC 开关稳压器 PMIC(电源管理集成电路)产品族中的产品是元器件级设备,用于需要稳定 DC 输入电压和/或将其转换为不同幅度的输出电压的应用。这些器件与称为“控制器”PMIC 的类似产品的区别在于集成了主开关元件,设备提供的电力会通过该元件。
