SC70 Inverting Charge Pumps with Shutdown
General Description
The MAX1852/MAX1853 monolithic,
CMOS chargepump
voltage inverters in the ultra-small SC70 package feature a low 15Ω output resistance, permitting loads up to 30mA with maximum efficiency.
The MAX1852/ MAX1853 are available with operating frequencies of 50kHz and 200kHz, respectively, allowing optimization of supply current or external component size.
Small external components and micropower shutdown mode make these devices ideal for both battery-powered and board-level
voltage conversion applications.
Oscillator control circuitry and four power-
MOSFET switches are included on-chip.
Applications include genera...
