The LTC®4355 is a positive voltage ideal diode-OR controller that drives two external N-channel MOSFETs. Forming the diode-OR with N-channel MOSFETs instead of Schottky diodes reduces power consumption, heat dissipation and
PC board area. With the LTC4355, power sources can easily be ORed together to increase total system reliability. The LTC4355 can diode-OR two positive supplies or the return paths of two negative supplies, such as in a –48V system.
In the forward direction the LTC4355 controls the voltage drop across the MOSFET to ensure smooth current transfer from one path to the other without oscillation. If a power source fails or is shorted, fast turnoff minimizes
reverse current transients. Power fault detection indicates if the input supplies are not in regulation, the inline fuses are blown, or the voltages across the MOSFETs are greater than the fault threshold.

Texas Instruments TPS73701DCQ
The TPS73701DCQ is a linear low-dropout (LDO) Voltage Regulator uses an NMOS pass element in a voltage-follower configuration. This topology is relatively insensitive to output capacitor value and ESR, allowing a wide variety of load configurations. Load transient response is excellent, even with a small 1µF ceramic output capacitor. The NMOS topology also allows very low dropout. This device uses an advanced BiCMOS process to yield high precision while delivering very low dropout voltages and low ground pin current. Current consumption, when not enabled, is less than 20nA and ideal for portable applications. This device is protected by thermal shutdown and fold-back current limit. It features reverse current blockage and freedom from output capacitor constraints. These features combined with an enable input makes the device ideal for portable applications.
- Thermal shutdown and current limit for fault protection
- Excellent load transient response-even with only 1µF output capacitor
- 1% Initial accuracy
- 3% Overall accuracy over line, load and temperature
- Less than 20nA typical IQ in shutdown mode
- Green product and no Sb/Br

Texas Instruments TPS767D301PWP
The TPS767D301PWP is a Dual-output Low-dropout (LDO) Voltage Regulator that offers fast transient response, low dropout voltages, dual outputs and incorporating stability with 10µF low ESR output capacitors. The TPS767D301 dual voltage regulator is designed primarily for DSP applications. This device can be used in any mixed-output voltage application, with each regulator supporting up to 1A. Dual active-low reset signals allow resetting of core-logic and I/O separately. Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low and is directly proportional to the output current. Additionally, since the PMOS pass element is a voltage-driven device, the quiescent current is very low and independent of output loading (typically 85µA over the full range of output current, 0mA to 1A). These two key specifications yield a significant improvement in operating life for battery-powered systems.
- Dual output voltages for split-supply applications
- Output current range of 0mA to 1.0A per regulator
- 3.3/2.5, 3.3/1.8 and 3.3V/Adjustable output

Analog Devices / Linear Technology LTM8064EY#PBF
The LTM®8064 is a 58VIN, 6A, constant-voltage, constantcurrent (CVCC), step-down µModule® (power module) regulator. Included in the package are the switching controller, power switches, inductor andsupport components. Operating over an input voltage range of 6V to 58V, the LTM8064 supports an output voltage range of 1.2V to 36V. CVCC operation allows the LTM8064 to accurately regulate its output current up to 7A when sourcing and 9.1A when sinking over the entire output range. The output current can be set by a control voltage, a single resistor or a thermistor. To set the switching frequency, simply place a resistor from the RT pin to ground. A resistor from FB to ground will set the output voltage. Only the bulk input and output filter capacitors are needed to finish the design.
