Constant 500kHz Switching Frequency Uses All Surface Mount Components Operates with Inputs as Low as 4V Saturated Switch Design (0.
3Ω) Cycle-by-Cycle Current Limiting Easily Synchronizable Inductor Size as Low as 2µH Shutdown Current: 20µA
with all the necessary oscillator, control and logic circuitry.
High switching frequency allows a considerable reduction in the size of external components.
The topology is current mode for fast transient response and good loop stability.
Both fixed output voltage (3.
3V) and adjustable parts are available.
A special high speed bipolar process and new design techniques allow ...
