一,产品概述(General Description)
      The JTM3416 are high-efficiency, high frequency synchronous step-down
DC-DC regulator ICs capable of delivering up to 1.5A output currents. The
JTM3416 can operate over a wide input voltage range from 2.3V to 5.5V and
integrate main switch and synchronous switch with very low RDS(ON) to minimize
the conduction loss.It is ideal for powering portable equipment that runs from a
single cell Lithium-Ion (Li+) battery. The output voltage can be regulated as low as
0.6V. The JTM3416 can also run at 100% duty cycle for low dropout operation,
extending battery life in portable system.This device offers two operation modes,
PWM control and PFM Mode switchingcontrol, which allows a high efficiency over
the wider range of the load.
      The JTM3416 is offered in a low profile (1mm)5-pin, thin SOT package, and
is available in an adjustable version.

五,产品封装图 (Package)

PIN	NAME	FUNCTION
1	RUN	Chip Enable Pin. Drive RUN above 1.5V to turn on the part. Drive RUN below 0.3V to turn it off. Do not leave RUN floating.
2	GND	Ground Pin
3	SW	Power Switch Output. It is the switch node connection to Inductor. This pin connects to the drains of the internal P-ch and N-ch MOSFET switches.
4	VIN	Power Supply Input. Must be closely decoupled to GND with a 10µF or greater ceramic capacitor.
5	VOUT	Output Voltage Feedback Pin. An internal resistive divider divides the output voltage down for comparison to the internal reference voltage.
