3ch DC/DC Converter with I²C Interface

and Internal SW FETs

S6AP412A contains 2ch buck DC/DC converter and 1ch buck-boost DC/DC converter. One of the buck DC/DC converter is

available for Multi-phase method. Multi-phase DC/DC converter is possible to load high current until 4A. S6AP412A can supply the

main power line in several systems by using only its chip. The current mode control is adopted for the DC/DC converter, and it is

possible to use the small chip inductor with the high switching frequency operation which contains internal switching FETs.

S6AP412A contains the output setting resistor and the phase compensation circuit, and contributes to reduce the number of

external components and its mount area. Also it contains the CTL input pin which can control the ON/OFF for each DC/DC converter,

the Power Good signal output pin and I²C communication interface, therefore it is easy to design the power supply sequence. It is

possible to tune in the output voltage exactly using the I²C communication.

Features

 Operating input voltage range: 2.5V to 5.5V (Maximum rating: 6.5V)

 Output voltage setting range:

DD1*:0.7V to 1.32V (20mV/step)

DD2*:1.2V to 1.95V (50mV/step)

DD3*:2.8Vto 3.5V (100mV/step)

 Maximum output current: DD1:4A, DD2:1.2A, DD3:0.6A

 Internal switching FETs, output voltage setting resistor, phase compensation circuit and output discharge resistor (all DC/DC

converters)

 Buck-boost DC/DC converter is seamless to change operation mode

 Soft start time setting range: 1 ms to 16 ms (approximately 1ms/step)

 Switching frequency for the DC/DC converter: 3 MHz

 Communication interface: I²C (ON/OFF, Output voltage, Soft start time)

 Internal PFM/PWM auto switching mode

 Each DC/DC converter Power Good function (open drain)

 Several protection functions: Under voltage lockout (UVLO), Over current protection (OCP), Thermal shut down (TSD)

 Small package: QFN32 (5mm × 5mm × 0.71mm, 0.5mm pitch)

*: DD1, DD2, DD3 : DC/DC converter block 1,2,3

Applications

Network equipment, Factory automation, Security system, Surveillance camera, Electrical music instrument, Multi-function printer,

Scanner, Printer, Copy machine, Home appliances,Data storage (HDD, SSD), Mobile equipment for Li+ battery (1 cell)
