HV9919BDB1
Single, High Current LED Driver Demoboard
Specications
The HV9919BDB1 demoboard is a high current LED
driver designed to drive one LED at 1.0A from a 9.0 -
16V DC input. The demoboard uses Supertex’s HV9919
hysteretic buck LED driver IC.
The HV9919BDB1 includes two PWM dimming modes.
The analog control of the PWM dimming mode allows
the user to dim the LED using a 0 - 2.0V analog signal
applied between the ADIM and GND pins (0V gives 0%
and 2.0V gives 100%). In this mode, the PWM dimming
frequency is set to 1kHz on the board. The digital control
of PWM dimming mode allows the user to dim the LEDs
using an external, TTL-compatible square wave source
applied between DIM and GND. In this case, the PWM
dimming frequency and duty ratio are set by the external
square wave source.
Parameter Value
Input voltage 9.0 - 16VDC (steady state)
40V max (transient)
Reverse polarity protection 60V (max)
Output voltage 2.0 - 5.0V
Output current 1.0A ± 5%
Output current ripple (@13.5V
input and 3.3V output) 16% (peak to peak)
Full load efciency
(@13.5V input) 84%
Open LED protection Yes
Output short circuit protection Yes
Dimensions 25.4mm X 25.4mm
General Description
Connection Diagram
Input Connection: Connect the input DC voltage between
VIN and GND terminals of connector J1 as shown in the
connection diagram.
Output Connection: Connect the LEDs between LED+
(anode of LED string) and LED- (cathode of LED string) of
connector J2.
PWM Dimming Connection:
1. If no PWM dimming is required, short DIM, VDD and
ADIM terminals of connector J3.
2. If dimming using an external PWM dimming source,
connect the PWM source between the DIM and GND
terminals of connector J3 and short terminals ADIM
and VDD. The recommended PWM dimming frequen-
cy is ≤1.0kHz.
3. If dimming using an external analog voltage source,
connect the source between the ADIM and GND ter-
minals of connector J3 and short terminals DIM and
VDD. The voltage range for control of the PWM dim-
ming is 0 - 2.0V.
