LED Driver for General Lighting
Highlight: BM520Qxx series for non-dimming applications
AC/DC controller IC to be used in a wide range of low-cost non-dimmable LED lighting applications.
Main target application is retrofit LED lighting (E27, E14, GU10, T8)
Key Features:
 Max 150kHz switching frequency (quasi-resonant)
 Buck topology for non-isolated system
 Integrated 650V MOSFET (with different RDSon)
 Peak current regulation with leading-edge blanking
 Optional NTC controlled thermal protection
 Thermal Shutdown Protection (TSD)
 Over Voltage Protection (OVP)
 Under Voltage Lock Out (UVLO)
Typical Application with BM520Qxx includes:
EMI filter
Valley boost circuit – input voltage drop protection
Supply circuit - ensures stable supply voltage at the VCC pin
AC/DC converter – controls the LED current
Works in quasi-resonant mode boosting efficiency and improving EMI
Highlight: BM555BKFV High-End solution for dimming applications
Key Features:
 AC voltage range 80…270VAC; <10% LED current ripple
 Average and/or peak current regulation in buck / fly-back topology
 Fixed frequency DC/DC 40…400kHz
Dimming compatibility
 Accurate 'true phase-cut' detector allows wide dimming range (<5%)
 Dynamic Load Current Controller (DLCC) function for stable operation with leading/trailing edge dimmers
 False LED activation prevention for mains-powered dimmers that require standby current
 Natural 'linear' dimming through logarithmic compensation
 Dimmer detector improves efficiency by turning off DLCC current if dimmer is not present
 Supports PWM and linear dimming (for non-retrofit LED lighting)
Internal IC supply voltage regulator
 Wide input supply voltage range 15~40V
 Low current consumption 2mA in operation
Safety & Protection
 Over Current Protection (OCP)
 Thermal Shut Down Protection (TSD)
 Under Voltage Lock Out Detection (UVLO)
For optimal performance with TRIAC /
electronic dimmers, the BD555BKFV has three
main individual functions:
1. ‘True’ phase-cut detector
2. Dynamic Load Current Controller
(DLCC)
3. DC/DC controller for average current
and/or peak current feedback

Voltage Detection / Reset ICs
The ROHM Semiconductor voltage detector IC series include a wide selection of Reset ICs with high accurate
detection of ±1% , low current consumption, small thin packages and wide range of detection voltages. They
can be used for every kind of application equipped with micro controllers, CPUs or DSPs. Both CMOS and open
drain output are available. Default SSOP packages are pin- and function-compatible, so they can be used as
replacement for existing IC. Besides, a lineup of very small and thin packages allows compact layout
implementation very close to the micro controllers.

EDLC Cell Balancing IC
BD14000EFV-C: EDLC Cell Balancing IC
ROHM Semiconductor offers the Industry’s First Monolithic EDLC Cell Balancing IC that contributes to increased
miniaturization, greater stability and longer life for EDLCs (Electric Double Layer Capacitors). The BD14000EFV-C
integrates over 20 discrete components required for EDLC cell balancing on a single chip. Reducing mounting area
by 38% over conventional solutions while eliminating component variations, making it easy to configure compact,
high reliability EDLC systems.
Key Features:
 Self-contained EDLC balancing function
 Supports 4 to 6 cells connected in series
 Shunt resistor method for simple cell balancing operation
 Adjustable detection voltage ensures compatibility with a
variety of EDLC output voltages (2.4 to 3.1 V in 0.1 V steps)
 Multi-stage IC connection possible, enabling easy scalability
 Reliable control/overvoltage detection and self-check
functions
 AEC-Q-100 Qualified
Specification
 Input Voltage Range: 8.0V to 24.0V
 Cell Detection Voltage: 2.4V to 3.1V
 Detection Accuracy:±1%
 Shunt switch FET incl.: 1Ω (Typ.)
 Ta: -40oC - 105oC
 HTSSOP-B30 (10.0 x 7.6 x 1.0 mm)

Applications:
 EVs, HEVs, and stop-start-equipped
vehicles
 Regenerative energy storage systems for
industrial machinery and construction
equipment
 Power stabilization devices such as UPS
*EDLC
(Electric Double Layer
Capacitor):
EDLCs or Supercapacitors
provide the highest capacitance
values per unit volume and the
greatest energy density of all
capacitors. They bridge the gap
between capacitors and
rechargeable batteries. While
existing EDLCs have energy
densities that are approximately
10% of a conventional battery,
their power density is generally
10 to 100 times higher. This
makes charge and discharge
cycles of EDLCs much faster than
batteries. Additionally, they
tolerate more charge and
discharge cycles than batteries.
