H-Bridge DC/DC Controller

TLD5190QV

Pin Configuration

36

INOVLO

I

Input Overvoltage Protection Pin;

Define an upper voltage threshold and switches OFF the device in case of

overvoltages on the VIN supply. Must not be left open.

20

VFB

I

Voltage Loop Feedback Pin;

VFB is intended to set output protection functions.

22

SET

I

Analog current sense adjustment Pin;

A voltage

V

SET between 0.2V and 1.5V will adjust the ILED or VOUT in a

linear relation.

37

SPREAD_SPECT

RUM

IPD Spread Spectrum Pin;

This pin is enabling and disabling the SPREAD SPECTRUM function. This

feature is beneficial to improve the EMC performance.

39

IINMON

O

Input current monitor output;

Monitor pin that produces a voltage that is 20 times the voltage VIN1-IN2.

IINMON will be equal 1V when VIIN1-VIIN2=50mV

16

IOUTMON

O

Output current monitor output;

Monitor pin that produces a voltage that is 200mV + 8 times the voltage

VFBH-FBL. IOUTMON will be equal 1.4V when VFBH-FBL = 150mV.

21

VREF

O

PD Voltage Reference Output Pin;

Supplies an accurate 2V output voltage for standalone analog dimming

and LED temperature compensation via external resistors. Bypass with an

external 100nF capacitor close to the pin. Pin must not be left open.

Logic Outputs

27

CLKOUT

O

Clock Output Pin;

Switching Oscillator output signal to supply additional SYNC Inputs of

other DCDC devices (beneficial for standalone operations without µC)

33

EF1

O

Error Flag 1;

An open drain output which is pulled to LOW when an output Short to GND

or Overtemperature occurs

32

EF2

O

Error Flag 2;

An open drain output which is pulled to LOW when an OPEN load,

Overvoltages or Overtemperature occurs

1) O: Output, I: Input,

PD: pull-down circuit integrated,

PU: pull-up circuit integrated
