MAX851 Datasheet Negative Charge-pump Power Supplies

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-0238; Rev 2; 4/96 Low-Noise, Regulated, Negative Charge-Pump Power Supplies for GaAsFET.

General Description

The MAX850–MAX853 low-noise, inverting, chargepump power supplies are ideal for biasing GaAsFETs in cellular telephone transmitter amplifiers.

The MAX850–MAX852 offer both preset (-4.1V) and adjustable (-0.5V to -9.0V) output voltages.

The MAX853 uses an external positive control voltage to set the negative output voltage.

Key Features

  • o Fixed -4.1V or Adjustable -0.5V to -9V Output at 5mA o 4.5V to 10V Input Voltage Range o 2mVp-p Output Voltage Ripple (MAX850.
  • MAX852) 1mVp-p Output Voltage Ripple (MAX853) o 100kHz Charge-Pump Switching Frequency (MAX850/MAX851/MAX853) o External Synchronizing Clock Input (MAX852) o Logic-Level Shutdown Mode: 1µA Max Over Temperature (MAX850/MAX852/MAX853) o Low Cost, 8-Pin SO Package MAX850.
