1MHz Step-Up PWM Converter with 5.5A Switch Current - AN3202

The AN3202 is a current-mode boost DC/DC converter with a 5.5A, 0.1Ω internal power MOSFET to provide this regulator highly power efficient. The AN3202 operates at 1MHz allowing for easy filtering and low noise. Internal compensation makes the user to set system easily, which allows the use of small, low-ESR ceramic output capacitors. Fault protection includes over-current latch off, input UVLO and thermal shutdown. This device uses current mode control scheme that provides fast transient response. In shutdown mode, the supply current is less than 1uA. The AN3202 is available in an SOP8-EP package, provides a very compact system solution and good thermal conductance.
