Product Details
The MAX889 IC is an inverting charge pump that delivers a regulated negative output voltage at loads up to 200mA. The device operates from an input of +2.7V to +5.5V to produce a user-adjustable, regulated output of -2.5V to -VIN.
The MAX889S evaluation kit (EV kit) is a fully assembled and tested surface-mount board. The board is set up to provide a -3.3V output from a +5.0V input supply. The EV kit is shipped with a MAX889S (1MHz switching frequency) installed. The board may also be used to evaluate the MAX889R (500kHz) or the MAX889T (2MHz). To do so, request a free sample of the MAX889RESA or MAX889TESA, and refer to the MAX889 data sheet for the appropriate capacitor values.
Applications
