Sales Briefcase
  • The RHRPMPOL01 is a single phase, step-down monolithic switching regulator with high precision internal voltage reference and integrated power MOSFETs for synchronous conversion. The device has been developed using SOI technology that offers good performance against SEL effect.

    The regulator converts 3.0 V to 12 V input voltage to 0.8 V to (0.85xVIN) output voltage. It has been designed to supply FPGA, DSP, MCU and ASICS in general for space applications.
    The controller is based on peak current mode architecture, which ensures a fast load transient response and very stable switching frequency. An embedded integrator compensates the DC voltage error due to the output voltage ripple. The fault management consists of not-latched output overvoltage protection, overcurrent protection and auto recovery thermal protection.

    Key Features

    • 3.0 V to 12 V input operating voltage range (target radiation performance guaranteed at VCC up to 7 V)
    • 0.8 V to (0.85xVIN) output voltage range
    • Up to 7 A output current
    • Wide operating temperature range -55 °C to +125 °C
    • Single supply
    • Integrated N-channel MOSFETs for synchronous step-down conversion
    • Integrated BOOT diode
    • Programmable switching frequency: from 100 kHz to 1 MHz
    • Fast load transient response and simple loop compensation based on peak current mode control loop
    • Easy synchronization with 180° out-of-phase (up to 2 ICs) management
    • Current sharing configuration for higher load requirements
    • Lossless current sensing based on sense-FET
    • Not-latched output overvoltage protection
    • Adjustable output overcurrent protection
    • Input undervoltage protection
    • Latched overtemperature protection
    • Power Good output pin
    • Programmable soft-start with increased current capability
    • Hermetic ceramic package qualified for space applications FLAT-28
    • Target radiation performance:
