Description

The R-78BXX-1.0 series high efficiency switching regulators are ideally suited to replace 78xx linear regulators and are pin compatible. The efficiency of up to 97% means that very little energy is wasted as heat so there is no need for any heat sinks with their additional space and mounting costs.

The L-Version with 90° pins allows direct replacement for laid-flat regulators where component height is at a premium. Low ripple and noise figures and a short circuit input current of typically only 10mA round off the specifications of this versatile converter series.

Features

1. Efficiency up to 97%,Non isolated, no need for heatsinks

2. Pin-out compatible with LM78XX Linears

3. Low profile( L*W*H=11.5*8.5*17.5mm)

4. Wide input range.(4.75V ~ 34V)

5. Short circuit protection, Thermal shutdow

6. Non standard outputs available as specia between 1.5V ~ 15V

7. Low ripple and noise

8. “L” version with 90° pins

9. See Innoline Application Notes for use as inverter (alternative to LM79xx Linear)

Part Number: MAX856CSA

Function: 3.3V/5V or Adjustable-Output, Step-up DC-DC Converter

Package: SO 8 Pin Type

Manufacturer: Maxim Integrated

Pinouts:

 

Description

The MAX856 thru MAX859 are high-efficiency, CMOS, step up, DC-DC switching regulators for small, low input voltage or battery-powered systems.

The MAX856CSA, MAX858 accept a positive input voltage between 0.8V and VOUT and convert it to a higher, pin-selectable output voltage of 3.3V or 5V. The MAX857/MAX859 adjustable versions
accept 0.8V to 6.0V input voltages and generate higher adjustable output voltages in the 2.7V to 6.0V range.

Typical efficiencies are greater than 85%. Typical quies cent supply current is 25µA (1µA in shutdown).

The MAX856 thru MAX859 combine ultra-low quiescent supply current and high efficiency to give maximum battery life. An internal MOSFET power transistor permits high switching frequencies. This benefit, combined with internally set peak inductor current limits, permits the use of small, low-cost inductors.

Features

1. 0.8V to 6.0V Input Supply Voltage

2. 0.8V Typ Start-Up Supply Voltage

3. 85% Efficiency at 100mA

4. 25μA Quiescent Current

5. 1μA Shutdown Mode
