AX3518 1MHz, 3.2A Synchronous Step-Down Converter
性能描述:
The AX3518 is a 1MHz constant frequency cu rrent mode PWM step- down converter. It
is ideal for portable equipment requiring very high current up to 3.2A from single-cell
Lithium-ion batteries while still achieving over 90% efficiency during peak load conditions.
The AX3518 also can run at 100% duty cycle for low dropout operation, extending battery
life in portable systems while light load operation provides very low output ripple for noise
sensitive applications. The AX3518 can supply up to 3.2A output load curr ent from a 2.8V to
5.5V input voltage and the output voltage can be regulated as low as 0.8V. The high
switching frequency minimizes the size of external components while keeping switching
losses low. The internal slope compensation setting allows the device to operate with
*aller inductor values to optimize size and provide efficient oper ation. The AX3518 is
available in adjustable (0.8V to VIN) output voltage. The device is available in SOP-8L-EP
and TDFN-8L Pb-free packages.
特点:
• 2.8V to 5.5V Input Voltage Range
• Output Voltages from 0.8V to VIN
• High Efficiency: Up to 94 %
• 1MHz Constant Frequency Operation
• With power saving mode
• Up to 3.2A Output Current
• No Schottky Diode Required
• Current Mode Operation for Excellent Line and Load Transient Response
• Current limit and therma l shutdown protection
• Short Circuit Protect (SCP)
• Build-in Soft Start function
• SOP-8L-EP and TDFN-8L Pb-Free packages
