Description
Provides control functions for powering vacuum fluorescent displays (VFDs) with minimal external components.
Quasi-resonant, discontinuous flyback converter operating near critical conduction boundary.
Adaptive turn-on control scheme optimizes turn-on and turn-off phases of MOSFET to reduce EMI and switching losses.
Self-oscillating converter with switching frequencies dependent on input voltage, load, and external components.
Onboard linear regulator powered by battery provides housekeeping supply.
Internal diagnostics protect against overloads, input undervoltage, and overtemperature conditions.
Features
Multiple output regulator
7 to 40 V input supply
Low EMI conducted and radiated emissions
Adaptive quasi-resonant turn-on/off control
Minimal number of external components
Enable input driven with respect to battery voltage
8-pin narrow SOIC package (suffix L)
Applications
Powering VFDs in automotive electronic control units (ECUs)
