MAX851 Negative Charge-Pump Power Supplies

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 vol.

MAX851 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-
