8 Detailed Description
The AS1390 is a high efficiency, high voltage and high current DC-DC Step-up controller combined with an Step-down converter. The device is
designed for LED backlight in LCD TV-sets. The special feature is the optimized operation point for the 2D and 3D mode. Hence the output
voltage of the Step-up Converter can easily be switched via the MODE_3D pin from one voltage to the other.

Setting output voltages
ch
ni
The Output voltages of the AS1390 are defined by a voltage divider between the FB pin and Vout. Due to the capability of the AS1390 to switch
between two output voltages, two dividers are necessary to adjust both output voltages.
Output voltage for 2D-Mode:
Te
R FB1
V OUT – 2D = V FB ×  1 + -------------------------------
R FB2 + R FB3
(EQ 1)
Output voltage for 3D-Mode:
R FB1 + R FB2
V OUT – 3D = V FB ×  1 + -------------------------------
R FB3
(EQ 2)
Where: VFB = 1.25V
Note: The overall resistance should be in the range of 100k to 200kΩ to avoid any noise issues.

8.1.2
Undervoltage-Lockout (UVLO)
To enable the usage of the circuit with a wide input voltage range (typ. 12V and 24V), the threshold for undervoltage detection should be
selectable by external components. Therefore a PAD UVLO is implemented, with an external resistor that selects the value of the threshold and
implements also a hysteresis. Till UVLOCO gets deactivated, the threshold is higher, after UVLOCO is 0 (no undervoltage condition), the
threshold is lowered by a switch-on of a constant current source.
If the undervoltage-lockout is not needeed connect the UVLO pin to VDDL.

Compensation Network
Te
8.1.9
For typical use cases a compensation network should be implemented by C10, C11 and R11 for 2D mode and optional by different component
values C12, C13, R13 for 3D mode (see Figure 18 on page 10).
A typical choice for values of the compensation network is C10 = 100pF, C11 = 10nF, R11 = 100KΩ. Use these values as initial choice and
evaluate the transient response of the system to verify the behavior at output load change. To be able to do a different compensation for 3D
mode, a second pin COMP_3D is available. If no separate compensation for 3D mode is necessary, PINs COMP_2D and COMP_3D can be
connected to one common compensation network.

8.2 Buck Converter
The buck converter of the AS1390 is working with high-efficiency at a constant-frequency. The buck converter is optimized to supply a µC and
with a fixed output voltage of 5V.
The buck converter is working as soon as the AS1390 is powered-up but offers an automatic power save mode. The highly efficient duty cycle
provides low dropout operation, which reduces the power consumption of the system.

id
8.3 Overvoltage Protection (OVP)
An overvoltage condition is detected when the feedback voltage is higher than the skip threshold (1.28V typ.). The device is than entering the
skip mode. Meaning the next pulse will be skipped and in the next cycle the overvoltage check is done again.

8.4 Overcurrent Protection (OCP)

on A
te G
nt
st
il
An overcurrent comparator is monitoring the output current via the sense pin. If an overcurrent condition occurs the transistor will be switched off
immediately. After the overcurrent condition is removed the device is returning to normal operation again.
8.5 Overtemperature Protection (OTP)
Te
ch
ni
ca
As soon as the junction temperature reaches approximately 140°C the AS1390 goes in thermal shutdown. In this mode the internal transistors
are turned off. The device will power up again, as soon as the temperature falls below +110°C again.

In order to reach the highest efficiency and best performance of the device we recommend to use the following external components.
Te
For the capacitors and resistors standard available components can be used. Depending on the desired voltage and the current special
inductors and transistors should be used to guarantee pest performance for high current and high voltage operation. For the transistor we
recommend the SIR432DP from Vishay Siliconix (www.vishay.com) for the Inductors see Table 4.
