HM3410C Datasheet PDF - Shenzhen Huazhimei Semiconductor Co., Ltd

■ Product Overview
   HM3410C is a CMOS step-down DC/DC regulator composed of a reference voltage source, an oscillator circuit, a comparator, and a PWM/PFM control circuit.
   The PWM/PFM automatic switching control circuit is used to achieve an adjustable duty cycle, and has the characteristics of low ripple, high efficiency, and large output current within the full input voltage range (1.8-5.5V).

■ Product Features
● High efficiency, maximum efficiency can reach 95%
● Large output current 800mA
● Very small quiescent current, typical value 40μA
● Very small output ripple <±0.4%
● Low voltage operation, up to 100% duty cycle
● PWM/PFM automatic switching, duty cycle automatically adjustable to maintain high efficiency and low ripple in a wide load range

■ Applications
● Power supply for mobile devices such as digital cameras, electronic notebooks, PDAs, etc.
● Power supply for audio devices such as CD players and MDs
● Regulated power supply for cameras, video equipment, and communication equipment
● Power supply for microcomputers
