R1242S Series 30 V Input 3 A Buck DC/DC Converter NO.EA-191-190718 OUTLINE The R1242S is a CMOS-based 30 V input, 3 A, synchronous rectified step-down DC/DC converter with built- in High-side switch. The R1242S contains Nch High-side Tr. (Typ. 0.1 ) and can supply maximum 3 A output current. In order to reduce heat generation caused by energy loss, FET can be used as Low-side switch. Low- side switch turns off when ICs shut down. The R1242S consists of the followings: an oscillator, a PWM control circuit, a voltage reference unit, an error amplifier, a phase compensation circuit, a slope control circuit, a soft- start circuit, protection circuits, an internal regulator, a switch, and so on. Also, the R1242S consists of the following external components: an inductor, resistors, an external FET, and capacitors. The R1242S operates with current mode topology, which does not require any sense resistor. As a result, the R1242S can achieve high speed and high efficiency. The oscillator frequencies for each version are set as follows adjustable between 330 kHz to 1000 kHz for versions A and B, 330 kHz for versions C and D, 500 kHz for versions E and F, and 1000 kHz for versions G and H. The R1242S is equipped with the protection functions, such as peak current limit function, latch function, fold back function, thermal-shutdown function, and undervoltage-lockout (UVLO) function. Peak current limit function restricts the maximum current into 4.5 A. Latch function (comes with versions A, C, E, and G) shuts off the output if current limit detection continues for a certain period of time. Fold back function (comes with versions B, D, F, and H) reduces the initial oscillator frequencies into 1/4 when output is short-circuited.
