INTERSIL launches H-bridge boost-buck regulator ISL9110

Intersil Company (NASDAQ Global Trading Code: Isil) launched a compact, high-efficiency 1.2A boost-buck regulator - isl9110, compact The size makes it ideal for battery powered devices such as handheld instruments, games, POS machine systems and similar applications. The ISL9110 can adjust the input voltage below or above the output voltage, automatic operation in boost or buck mode, providing a stable output voltage to help simplify design. This regulator only needs an inductor and two capacitors to minimize the number of external components. Its output voltage transient deviation during the conversion of boost and buck mode is controlled at the lowest level in the industry, and its automatic lift buck mode switching function also enables designers to flexibly select optimal output voltages. The 2.5MHz switching frequency of the ISL9110 is also the highest frequency level in the same kind of boost-buck regulator, and further controls the size of the external component to the lowest level. The device can provide an output current of more than 2A (2VOUT) or 1.2A (3.0 VOUT) through a single lithium battery, providing the industry's highest level output current capability in the 3x3 mm occupying area. The adjustable version of the ISL9110 can be set to an output voltage as low as 1V by an external feedback resistor, which is an important function of the RF power amplifier or the like. More characteristics and advantages · The input voltage can be as low as 1.8V (very suitable for systems with alkaline or nickel-hydrogen batteries) · The efficiency of the buck can reach 95%. · Integrated overcurrent, undervoltage and over temperature protection · Mode / SYNC pin controls PFM / PWM operating mode and switching frequency · The switching frequency can be synchronized to 3.25MHz Pricing and supply The ISL9110 uses a compact 12-pin, 3x3 mm TDFN package, is now available. Support the fixed output voltage 3.3V or 5.0V, or adjust the output voltage. A single price of US $ 2.08, 1000 pieces.
