Description
The TLD5085EJ is a smart LED buck converter with an integrated power-switch, capable of driving up to 1.8A load
current with excellent line and load regulation. The main function of this device is to step-down the input voltage
and regulating a constant LED current. The constant current regulation is especially beneficial for LED color
accuracy and longer lifetime. The TLD5085EJ also has a PWM input which can be used for LED dimming. The
switching frequency of 370kHz allows to use small and inexpensive passive components. An Enable function is
implemented to reduce the shut-down current consumption to typ. 0.1µA. This IC is suited for use in the harsh
automotive environments and provides protection functions such as current limitation and overtemperature
shutdown. The integrated soft-start feature avoids a current and voltage overshot at the output during start-up of
the device.

Description
The gate of the power-switch is driven by the Gate driver which is supplied by the external capacitor connected to
pin BDS (Buck Driver Supply) using the bootstrap principle.
BDS is the supply pin for the integrated gate driver of the internal power-switch. The power-switch has to be
in the RDSon region. If VGS is not high enough, the power-switch can not operate in the RDSON region, which
means high power dissipation. An integrated under voltage lockout function (BDS UV-Comparator)
supervising the ’bootstrap’ capacitor voltage ensures that the device is always driven with a sufficient
bootstrap voltage in order to prevent from extensive heat up of the power-switch.
An integrated charge pump supports the gate driver in case of low input supply voltage, small differential
voltage between input supply and output voltage at low current and during startup. In order to minimize
emission, the charge pump is switched off if the input voltage is sufficient for supplying the bootstrap.
The soft start function generates a defined ramp of the reference voltage during the first 0.5 ms (typ.) after
device initialization and if the Device is autorestarting after a thermal shutdown. This function is disabled
during the dimming operation via the PWMI-pin.

Enable, Thermal Shutdown and PWM Dimming Function
6.1
Description
Enable Function
With the enable pin (EN) the device can be set in off-state reducing the current consumption to typ. 0.1µA. The
enable function features an integrated pull down resistor which ensures that the IC is shut down and the powerswitch is off in case the pin EN is not connected.
Device Wake Up Behavior
The device initialization is triggered either by the EN voltage level crossing the turn-on threshold, rising supply
voltage (during EN=H), and also when the device restarts after a thermal shutdown. The softstart ramp starts
after the BDS external capacitor is charged.
Overtemperature Behaviour
The integrated thermal shutdown function turns the power-switch off in case of overtemperature. The typ. junction
shutdown temperature is 175°C, with a min. of 150°C. After cooling down the IC will automatically restart
operation. The thermal shutdown is an integrated protection function designed to prevent IC destruction when
operating under fault conditions. It must not be used for normal operation.
PWM Dimming Function
The PWMI signal directly controls the gate driver of the integrated power-switch by overriding the internal control
signals.

Application Information
Note: The following information is given as a hint for the implementation of the device only and shall not be
regarded as a description or warranty of a certain functionality, condition or quality of the device.
8.1
Frequency Compensation
The stability of the output voltage can be achieved with a simple RC connected between pin COMP and GND.
The standard configuration using the switching frequency of the internal oscillator is a ceramic capacitor
CCOMP = 22nF and RCOMP = 22kW. By slight modifications to the compensation network the stability can be
optimized for different types of buck capacitors (ceramic or tantalum).
The compensation network is essential for the control loop stability. Leaving pin COMP open might lead to an
instable operation.
8.2
Compensating a Tantalum Buck Capacitor CBU1
The TLD5085EJ control loop is optimized for ceramic buck capacitors CBU. In order to maintain stability also
for tantalum capacitors with ESR up to 300mΩ, an additional compensation capacitance CCOMP2 at pin COMP
to GND is required. Its value is calculated as follows:
(8.1)
C COMP 2 =
C BU ⋅ ESR (C BU )
RCOMP
whereby CCOMP2 needs to stay below 5nF.

Freewheeling Diode
In order to minimize losses and for fast recovery, a Schottky freewheeling diode is required. Disconnecting the
freewheeling diode during operation might lead to destruction of the IC.

The output voltage of the TLD5085EJ can be programmed by a voltage divider connected to the feedback pin FB.
The divider cross current should be 300 µA at minimum, therefore the maximum R2 is calculated as follows:
(8.2)
R2 ≤
0 . 6V
V FB
→ R2 ≤
= 2 kΩ
300 µA
IR2
For the desired output voltage level VCC, R1 is calculated thus (neglecting the small FB input current):
