The Analog Devices MAX1761EEE is a dual pulse-width-modulation (PWM) step-down controller. It provides high efficiency, excellent transient response, and high DC output accuracy in a compact circuit topology. These features are essential for stepping down high-voltage batteries to generate low-voltage CPU core, I/O, and chipset RAM supplies in space-critical applications like notebook computers and smartphones.
Maxim’s proprietary Quick-PWM control scheme handles wide input/output voltage ratios and provides instant-on response to load transients while maintaining a relatively constant switching frequency. The MAX1761 achieves high efficiency by eliminating the current-sense resistor and employs a complementary MOSFET output stage, reducing component count. It is intended for CPU core, chipset, DRAM, or other low-voltage supplies.
The device features a 5V to 20V input range and operates with a switching frequency of 250kHz or 350kHz. It offers ±1% total DC error in forced-PWM mode and includes an Enable control feature. The MAX1761 is available in a 16-pin QSOP package, suitable for surface mount applications.
Applications include notebooks, PDAs, digital cameras, handy-terminals, and smartphones requiring 1.8V/2.5V logic and I/O supplies.
