R1240x Series 1.2 A, 30 V Step-Down DC/DC Converter NO.EA-190-170609 OUTLINE The R1240x is a CMOS-based Step-down DC/DC converter with internal Nch high side Tr. (0.35 ), which can provide the maximum 1.2 A output current. The ICs consists of an Oscillator, a PWM control circuit, a Reference Voltage unit, an Error amplifier, phase compensation circuits, a slope circuit, a s-ofsttart circuit, protection circuits, internal voltage regulators, and a switch for boot strap circuit. The ICs can make up a Step- Down DC/DC Converter with the following external components: an inductor, resistors, a diode, and capacitors. The R1240x is a current mode operating type DC/DC converter which does not require external current sense resistor, and i tworks high speed response time, high efficiency and compatible with ceramic capacitors. Oscillator frequency is internally set at 1.25 MHz. As a protection function, it has cycle by cycle peak current limit function, short protection function, thermal shutdown function and UVLO. There are two types for short protection, A version has latch protection function with 2m s delay time, and B version has fold-back protection function that keep operating at short condition with lower operating frequency and limiting the Lx current.
