MAP3621
Description
Features
MAP3621 is a single channel average-mode current control buck controller for LED backlight application. It does not require an additional dimming MOSFET and utilizes constant off-time control and average current control feedback without external loop pensation or high-side current sensing.
MAP3621 features
±1% CS voltage accuracy and has dedicated Independent analog dimming input up to 3.3V. It can be powered from 8.5V ~ 18V supply.
MAP3621 provides MOSFET DS short (FLT output), sense resistor short protection, SCP and UVLO.
MAP3621 is available 14 leads SOIC with Halogenfree (fully Ro HS pliant).
