19-0190; Rev 0; 9/93 3.3V, Step-Down, Current-Mode PWM DC-DC Converters __________________General Description The MAX748A/MAX763A are 3.3V-output CMOS, stepdown switching regulators. The MAX748A accepts inputs from 3.3V to 16V and delivers up to 500mA. The MAX763A accepts inputs between 3.3V and 11V and delivers up to 500mA. Typical efficiencies are 85% to 90%. Quiescent supply current is 1.4mA (MAX763A), and only 0.2µA in shutdown. Pulse-width-modulation (PWM) current-mode control provides pre.

Description 8th-Order / Lowpass / Butterworth / Switched-Capacitor Filter
Datasheet MAX748A DatasheetMAX7480 Datasheet (PDF)

19-1416; Rev 0; 1/99 8th-Order, Lowpass, Butterworth, Switched-Capacitor Filter General Description The MAX7480 8th-order, lowpass, Butterworth, switched-capacitor filter (SCF) operates from a single +5V supply. The device draws only 2.9mA of supply current and allows corner frequencies from 1Hz to 2kHz, making it ideal for low-power post-DAC filtering and anti-aliasing applications. The MAX7480 features a shutdown mode, which reduces the supply current to 0.2µA. Two clocking options are availa.

3.3V / Step-Down / Current-Mode PWM DC-DC Converters

19-0190; Rev 0; 9/93 3.3V, Step-Down, Current-Mode PWM DC-DC Converters __________________General Description The MAX748A/MAX763A are 3.3V-output CMOS, stepdown switching regulators. The MAX748A accepts inputs from 3.3V to 16V and delivers up to 500mA. The MAX763A accepts inputs between 3.3V and 11V and delivers up to 500mA. Typical efficiencies are 85% to 90%. Quiescent supply current is 1.4mA (MAX763A), and only 0.2µA 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. A 22µH inductor works in most applications, so no magnetics design is necessary. The MAX748A/MAX763A also feature cycle-by-cycle current limiting, overcurrent limiting, undervoltage lockout, and programmable soft-start protection. The MAX748A is available in 8-pin DIP and 16-pin wide SO packages; the MAX763A comes in 8-pin DIP and SO packages. ________________________________Features o Up to 500mA Load Currents o Guaranteed 159kHz to 219.5kHz Current-Mode PWM o 85% to 90% Efficiencies o 1.7mA Quiescent Current (MAX748A) 1.4mA Quiescent Current (MAX763A) o 0.2µA Shutdown Supply Current o 22µH Preselected Inductor Value; No Component Design Required o Overcurrent, Soft-Start, and Undervoltage Lockout Protection o Cy.
