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.
