MAX738AEPA+

MAXIM INTEGRATED PRODUCTS  MAX738AEPA+  芯片, 直流/直流转换器, 降压, 5V, PWM

The is a 5V, step down, current mode PWM DC to DC converter in 8 pin DIP package. The MAX738A accept inputs from 6V to 16V and deliver 750mA. Typical efficiencies are 85% to 96%. Quiescent supply current is 1.7mA and only 6µA in shutdown. Pulse width modulation PWM current mode control provides precise output regulation and excellent transient responses. Output voltage accuracy is ±5% over line, load and temperature variations. Fixed frequency switching allows easy filtering of output ripple and noise using small external components.
