19-1305; Rev 1; 8, 98 Switched-Capacitor Voltage Doublers General Description The ultra-small MAX1682, MAX1683 monolithic, CMOS charge-pump voltage doublers accept input voltages ranging from +2.0V to +5.5V. Their high voltage-conversion efficiency (over 98%) and low operating current (110 A for MAX1682) make these devices ideal for both battery-powered and board-level voltage-doubler applications. Oscillator control circuitry and four power MOSFET switches are included on-chip. The MAX1682 ope

19-0809; Rev 0; 4, 07 High-Voltage, High-Power LED Driver with Analog and PWM Dimming Control General Description The MAX16831 is a current-mode, high-brightness LED (HBLED) driver designed to control two external n-channel MOSFETs for the single-string LED current regulation. The MAX16831 integrates all the building blocks necessary to implement fixed-frequency HBLED drivers with wide-range dimming control. The MAX16831 is configurable to operate as a step-down (buck), step-up (boost), or step
