The iP1837 and iP1827 iPowIR voltage regulators suit POL applications including servers, netcom, data storage, and telecom equipment requiring high current. They integrate a control MOSFET, synchronous FETKY, bootstrap diode, bootstrap capacitor and internal over-current protection in a 7.7 x 7.7-mm LGA wireless package.
The voltage regulators feature differential voltage sensing, +/- 0.5% reference voltage, over-voltage protection, dead time trim, and body braking to optimize transient response. The iP1837 and iP1827 are pin compatible for 25- and 35-A applications and offer a 1.5 to 16-V input voltage range and a programmable frequency up to 1.5 MHz. (Ea/100,000: iP1837, $5.90; iP1827, $4; reference design kit, $94 — available now.)
