High switching frequency (640kHz or 1.2MHz selectable) allows easy filtering and faster loop performance. An external compensation pin provides the user flexibility in determining loop dynamics, allowing the use of small, low equivalent-series-resistance (ESR) ceramic output capacitors. The.

19-3495; Rev 0; 11/04 High-Voltage, Low-Power Linear Regulators for Notebook Computers General Description The MAX8718/MAX8719 are micropower, 8-pin TDFN linear regulators that supply always-on, keep-alive power to CMOS RAM, real-time clocks (RTC), and microcontrollers in systems with high-voltage batteries. The circuits consist of a 100mA linear regulator and a power-good comparator (PGOOD) with fixed-output delay. Key features include wide input voltage range, low-dropout voltage, and low-quiescent supply current. Despite a miserly 25µA (max) no-load quiescent current, the MAX8718/MAX8719 have good line- and loadtransient response and excellent AC power-supply rejection. They provide a cl.

19-3569; Rev 2; 4/07 EVAALVUAAILTAIOBNLEKIT Interleaved High-Efficiency, Dual Power-Supply Controllers for Notebook Computers MAX8716/MAX8717/MAX8756/MAX8757 General Description The MAX8716/MAX8717/MAX8756/MAX8757 are dual, step-down, interleaved, fixed-frequency, switch-mode power-supply (SMPS) controllers with synchronous rectification. The MAX8716/MAX8717/MAX8756/MAX8757 are intended for main (5V/3.3V) power generation, while the MAX8756 is optimized for I/O power rails in batterypowered systems. Fixed-frequency operation with optimal interleaving minimizes input ripple current from the lowest input voltages up to the 26V maximum input. Optimal 40/60 interleaving allows the input voltag.

An external compensation pin provides the user flexibility in determining loop dynamics, allowing the use of small, low equivalent-series-resistance (ESR) ceramic output capacitors. The device can produce an output voltage as high as 12V from an input as low as 2.6V. Soft-start is programmed with an external capacitor, which sets the input-current ramp rate. In shutdown mode, current consumption is reduced to 0.1µA. The MAX1790/ MAX8715 are available in a space-saving 8-pin µMAX® package. The ultra-small package and high switching frequency allow the total solution to be less than 1.1mm high. µMAX is a registered trademark of Maxim Integrated Products, Inc. Ordering Informati.
