MAP3612

MAP3612 – 2-CH Average Current Control Buck Controller for LED Backlight Datasheet Version 1.0 MAP3612 2-CH Average Current Control Buck Controller for LED Backlight General Description Features MAP3612 is a 2 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 compensation or highside current sensing. MAP3612 features ±1% CS voltage accuracy and has dedicated analog dimming input up to 3V. It can be powered from 8.5V ~ 18V supply. MAP3612 provides MOSFET DS short detection(FLT output), SCP, ODP and UVLO. MAP3612 is available 16 leads SOIC with Halogenfree (fully RoHS compliant).  8.5V to 18V Input Voltage Range  Average-Mode Current Control  Programmable Constant Off-time  Independent Setting per Channel  Up to 3V Analog Dimming Input  1% CS Voltage Accuracy  Independent Direct PWM Dimming Input  Fault Output  MOSFET Drain-Source Short  Short Circuit Protection  Over-Duty Protection  UVLO  16 Leads SOIC Package with Halogen-free Applications  High Brightness white LED backlighting for LCD TVs  General LED lighting applications Ordering Information Part Number MAP3612SIRH Top Marking MAP3612 Ambient Temperature Range -40℃ to +85℃ 1 Typical Application Package 16Leads SOIC RoHS Status Halogen Free VCC SEL MODE PWM1 PWM2 ADIM TOFF1 TOFF2 GATE1 GATE2 CS1 CS2 PGND1 PGND...
