The is a high-efficiency monolithic synchronous Buck Regulator whose output is programmed with just one external resistor. The accurate internally generated 50µA current source on the ISET pin allows the use of a single external resistor to program an output voltage that ranges from 0 to 0.5V below VIN. The VOUT voltage feeds directly back to the error amplifier in unity gain fashion and equals the ISET voltage. The operating supply voltage range is 4 to 15V, making it suitable for dual lithium-ion battery and 5 or 12V input point-of-load power supply applications. The operating frequency is synchronizable to an external clock or programmable from 200kHz to 4MHz with an external resistor. High switching frequency allows the use of small surface mount inductors. The unique constant on-time architecture is ideal for operating at high frequency in high step-down ratio applications that also demand fast load transient response.
