Overview
MAX1816/MAX1994 19-2569; Rev 0; 10/02 Dual Step-Down Controllers Plus LinearRegulator Controller for Notebook Computers General Description The MAX1816/MAX1994 are dual step-down controllers for notebook computer applications.
BUCK1 is a CPU core regulator with dynamically adjustable output, ultrafast transient response, high DC accuracy, and high efficiency.
BUCK2 is an adjustable step-down regulator for I/O and memory supplies.
Both regulators employ Maxim’s proprietary Quick-PWM™ control architecture.
This fastresponse, constant-on-time PWM control scheme handles wide input/output voltage ratios with ease and provides 100ns “instant” on-response to load transients, while maintaining a relatively constant switching frequency.
The MAX1816/MAX1994 also have a linear-regulator controller for low-voltage auxiliary power supplies.
The CPU regulator supports “active voltage positioning” to reduce output bulk capacitance and lower power dissipation.
A programmable gain amplif...
