This IC is able to supply up to 2.4A of load current within the very wide range from 2.5V to 42V in the input voltage. This IC has an operation mode that is automatically changed to PFM operation during low load, which can achieve super-high efficiency with a very low quiescent current 20 A. It is possible to provide stable output voltage from an automotive cold cranking and load dump, up to 42V, conditions within 1 ms transition time. As a result, this IC is suitable for power supply solutions of automotive and Industrial applications. This IC has the SYNC function, which is capable of selecting the SYNC_IN that is able to inputs an external clock signal or the SYNC_OUT that is able to output an internal clock. When selecting the SYNC_IN and an external clock signal in the range from 200 kHz to 400 kHz is inputted, the FETs perform the switching operation with synchronizing signal from an external clock. When selecting the SYNC_IN and an external clock signal is not inputted, the FETs perform the switching operation from an internal clock. When selecting the SYNC_OUT, this IC provides a clock signal generated inside to external devices. The internal clock signal in the range from 200 kHz to 2.1 MHz can be set by an external resistor. Since external voltage setting resistors and phase compensation capacitors are not required with this IC, it can reduce the number of parts and a part mounting area. This IC has five protection functions, input under voltage lockout (input UVLO), output under voltage protection (output UVP), output over voltage protection (output OVP), output over current protection (output OCP), and thermal shutdown (TSD). Moreover, this IC has the power good (PG) function that indicates the state of the output voltage (VOUT pin). When the output voltage reaches the PG voltage, the PG signal is outputted. Also, the power-on reset time for the PG signal is selectable. The VOUT output voltage, SYNC function, VOUT UVP threshold, VOUT OVP threshold, power-on reset time of this product are selectable from the product lineup (refer to the "1. Product Lineup").

Functional Description 8.1 Block Description Input Under Voltage Lockout (Input UVLO) The input UVLO is the function that prevents a malfunction of this IC from the following status, and protects poststage devices. Transitional state at start-up drop of power supply voltage To prevent such a malfunction, this protection monitors the VIN input voltage and VCC voltage. When either VIN or VCC voltage falls to the UVLO falling threshold, 2.4V (Typ), or lower, the IC stops the VOUT voltage output and becomes UVLO status. When both VIN and VCC voltages reach the UVLO rising threshold, 4.75V (Typ), or higher, the IC is released from the UVLO state and returns to the normal operation. Momentary Output Under Voltage Protection (Output UVP) The output UVP is the function that monitors the voltage drop of the VOUT pin and notifies by the PG pin. When the output voltage falls to the UVP falling threshold (PGUVPHL) for the output voltage setting or lower, the PG voltage is fixed to the low level. The IC becomes the UVP status, but the switching operation is maintained under the UVP status. When the output voltage once again reaches the UVP rising threshold (PGUVPLH) for the output voltage setting or higher, the IC is released from the UVP state and the PG voltage is fixed to the high level. Output Over Voltage Protection (Output OVP) The output OVP is the function that monitors the voltage rise of the VOUT pin and stops the switching operations, which protects poststage devices from overvoltage. Also, the VOUT state is notified by the PG pin. When the output voltage rises to the OVP falling threshold (PGOVPLH) for the output voltage setting or higher, the PG voltage is fixed to the low level. The IC becomes the OVP status, and the switching operations of the high-Side FETs are stopped. When the output voltage once again falls to the OVP falling threshold (PGOVPHL) for the output voltage setting or lower, the IC is released from the OVP state and resumes the switching operations. The PG voltage is fixed to the high level again. Output Over Current Protection (Output OCP) The output OCP is the function that limits the excessive current load and protects poststage devices. Thermal Shutdown (TSD) The TSD is the function that protects the IC from heat-destruction. When the junction temperature reaches +165C (Typ), the high-side and low-side switching FET are turned off and the IC becomes the TSD status. When the junction temperature once again falls to +155C (Typ) or lower, the IC is released from the TSD state and restarts the power supply.

Usage Precaution Printed circuit board ground lines should be set up with consideration for common impedance. Take appropriate measures against static electricity. Containers for semiconductor materials should have anti-static protection or be made of conductive material. mounting, printed circuit boards should be stored and shipped in conductive bags or containers. Work platforms, tools, and instruments should be properly grounded. Working personnel should be grounded with resistance of 250 k to 1 M in serial body and ground. After Do not apply negative voltages. The use of negative voltages below -0.3 V may make the parasitic transistor activated to the LSI, and can cause malfunctions. 13.
