SNVS294S –NOVEMBER 2004–REVISED MAY 2016
LM3671/-Q1 2-MHz, 600-mA Step-Down DC-DC Converter Features
LM3671-Q1is Qualified for Automotive
Applications AEC Q100-Qualified With the Following Results Device Temperature Grade1: –40°Cto
+125°C Ambient Operating Temperature
Range 16-µA Typical Quiescent Current 600-mA Maximum Load Capability 2-MHz PWM Fixed Switching Frequency (Typical) Automatic PFM-PWM Mode Switching Internal Synchronous Rectificationfor High
Efficiency Internal Soft Start 0.01-µA Typical Shutdown Current Operates froma Single Li-Ion Cell Battery Only Three Tiny Surface-Mount External
Components Required (One Inductor, Two
Ceramic Capacitors) Current Overload and Thermal Shutdown
Protection Availablein Fixed Output Voltages and Adjustable
Version Applications Mobile Phones PDAs MP3 Players W-LAN Portable Instruments Digital Still Cameras Portable Hard Disk Drives Automotive Equipment Terminals Equipment Description
The LM3671 step-down DC-DC converter is
optimized for powering low voltage circuits froma
single Li-Ion cell battery and input voltage rails from
2.7Vto 5.5V.It providesupto 600-mA load current,
over the entire input voltage range. There are several
different fixed voltage output options availableas well an adjustable output voltage
1.1Vto 3.3V.
The device offers superior features
for mobile phones and similar
Automatic intelligent switching between
noise and PFM low-current mode
system control. During PWM
operates ata fixed-frequency of2 MHz (typical).
Hysteretic PFM mode extends the battery life by
reducing the quiescent current to 16 µA (typical)
during light load and standby operation. Internal
synchronous rectification provides high efficiency
during PWM mode operation.In shutdown mode, the
device turns off and reduces battery consumptionto
0.01 µA (typical). high-switching frequencyof2 MHz (typical) allows
useof tiny surface-mount components. Only three
external surface-mount components, an inductor, and Typical Application Circuit: ADJ
