MAX7444ESA
MAX7444ESA - Brand New Maxim Integrated Active Filters
- One-month free return and one year warranty.
- Full or Partial Refund, if the item is not as described
- Full Refund if you don't receive your order
General Description
The MAX730A/MAX738A/MAX744A are 5V-output CMOS, step-down switching
regulators. The MAX738A/MAX744A accept inputs from 6V to 16V and deliver
750mA. The MAX744A guarantees 500mA load capability for inputs above 6V and
has tighter oscillator frequency limits for low-noise (radio) applications.
The MAX730A accepts inputs between 5.2V and 11V and delivers 450mA for inputs
above 6V. 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
guaranteed to be ±5% over line, load, and temperature variations. Fixed-
frequency switching allows easy filtering of output ripple and noise, as well
as the use of small external components. These regulators require only a
single inductor value to work in most applications, so no inductor design is
necessary.
The MAX730A/MAX738A/MAX744A also feature cycle by-cycle current limiting,
overcurrent limiting, undervoltage lockout, and programmable soft-start
protection.
