HV9911NG-G-M901 More Semiconductors - ICs by Microchip Technology

Switch-Mode LED Driver IC w/ High Current Accuracy


The HV9911 is a current mode control LED driver IC designed to control single switch PWM converters (buck, boost, buck-boost, or SEPIC), in a constant frequency or constant off-time mode. The controller uses a peak current control scheme, (with programmable slope compensation), and includes an internal transconductance amplifier to control the output current in closed loop, enabling high output current accuracy. In the constant frequency mode, multiple HV9911s can be synchronized to each other, or to an external clock, using the SYNC pin. Programmable MOSFET current limit enables current limiting during input under voltage and output overload conditions. The IC also includes a 0.2A source and 0.4A sink GATE driver for high power applications. An internal 9.0 - 250V linear regulator powers the IC, eliminating the need for a separate power supply for the IC. HV9911 provides a TTL compatible, PWM dimming input that can accept an external control signal with a duty ratio of 0-100% and a frequency of up to a few kilohertz. The IC also provides a FAULT output which, can be used to disconnect the LEDs in case of a fault condition, using an external disconnect FET. The HV9911 based LED driver is ideal for RGB backlight applications with DC inputs. The HV9911 based LED lamp drivers can achieve efficiency in excess of 90% for buck and boost applications.
