Input waveform condition
I2C control transmission method
In start and stop conditions of the I2C bus, SDA should be kept in the constant state while SCL is "H" as
shown below during data transfer.
When data transfer is not made, both SCL and SDA are in the "H" state.
When SCL = SDA="H", change of SDA from "H" to "L" enables the start conditions to start access.
When SCL is "H", change of SDA from "L" to "H" enables the stop conditions to stop access.
No.A2349-10/15
LV52130A0XA/4XA
Data transfer and acknowledgement response
After establishment of start conditions, Data transfer is made by one byte (8 bits). Data transfer enables
continuous transfer of any number of bytes. Each time of the 8-bit data is transferred, the ACK signal is sent
from the receive side to the send side. The ACK signal is issued when SDA(on the send side) is released and
SDA(on the receive side) is set "L" immediately after fall of the clock pulse at the SCL eighth bit of data transfer
to "L". When the next 1-byte transfer is left in the receive state after transmission of the ACK signal from the
receive side, the receive side releases SDA at fall of the SCL ninth clock. In the I2C bus, there is no CE signal.
Instead, 7-bit slave address is assigned to each device and the first byte of transfer is assigned to the
command (R/W) representing the 7-bit slave address and subsequent transfer direction. Note that only WRITE
is valid in this IC. The 7-bit address is transferred sequentially from MSB and the eighth bit is "L" representing
WRITE.

Detailed Descriptions
The LV52130Ax has dual-output VOUT1 (LDO) and VOUT2 (built-in inverter charge pump) with 1coil boost
dcdc converter. Both outputs are separately controlled by I2C control and pin EN1/EN2. Boost converter is a
fixed-frequency pulse width modulated (PWM) regulator. At rated load, each converter operates at continuous
conduction mode (CCM). At light loads, both converters can enter in discontinuous conduction mode (DCM).
Cycle-by-cycle peak current limit and thermal provide value added features to protect the device.
No.A2349-11/15
LV52130A0XA/4XA
Start Sequencing
Enable input (pin EN1/EN1) is used as enable input logic. An active high logic level on this pin enables the
device. A built-in pull-down resistor disables the device if the pin is left open. If a high logic signal is applied, the
LV52130Ax starts with timing sequence as depicted Figure 4 (Case1/Case2).
It must be set ( 5.4V≥VOUT1 bit / VOUT2 bit≥-5.4V) and (VOUT1 current < 100mA) at start sequencing.
Fig.4 Sequencing Diagram
Inductor Selection
Three different electrical parameters need to be considered when selecting an inductor, the value of the
inductor, the saturation current and the DCR. During normal and heavy load operation, the LV52130Ax is
intended to operate in Continuous Conduction Mode (CCM). The equation below can be used to calculate the
peak current.
Ipeak_p = Iout1 / (n1 x ( 1- D1 )) + ( VIN x D1 ) / 2 x L1 x Fosc1
VIN:battery voltage, IOUT1:load current, L:inductor value, Fosc1: OSC frequency1, D1:duty cycle,
n1:converter efficiency varies with load current.
A good approximation is to use η = 0.85. It is important to ensure that the inductor current rating is high
enough such that it not saturate. As the inductor size is reduced, the peak current for a given set of conditions
increases along with higher current ripple so it is not possible to deliver maximum output power at lower
inductor values. Finally an acceptable DCR must be selected regarding losses in the coil and must be lower
than 250 mΩ (typical) to limit excessive voltage drop. In addition, as DCR is reduced, overall efficiency will
improve. The inductor value is recommended to use a 4.7 uH or 2.2uH.
