1MHz Step-Up PWM Converter
Description
AN3203
1MHz Step-Up PWM Converter with 2.
5A Switch Current
General Description
Features
The AN3203 is a current-mode boost DC/DC Adjustable Output Voltage up to 18V
converter with a 2.
5A, 0.
18Ω internal power Internal 0.
18Ω, 2.
5A, 18V Power MOSFET
MOSFET to provide this regulator highly power Internal Soft-Start
efficient.
The AN3203 operates at 1MHz allowing Fixed 1MHz Switching Frequency
for easy filtering and low noise.
Internal Current Mode Operation
compensation makes the user to set system easily, Cycle-by-Cycle current limit
which allows the use of small, low-ESR ceramic Adjustable Over Current Protection
output capacitors.
Input Under Voltage Lockout
Fault protection includes over-current latch off, Over-Temperature Protection
input UVLO and thermal shutdown.
This device RoHS Compliant
uses current mode control scheme that provides
fast transient response.
In shutdown mode, the Application
supply current is less than 1u...
