MAX1685 Description
The MAX1684/MAX1685 are high-efficiency, internalswitch, PWM step-down switching regulators intended to power cellular phones, municating PDAs, and handy-terminals. These devices deliver a guaranteed 1A output current from two Li-Ion batteries. Their wide input voltage range of 2.7V to 14V gives design flexibility and allows batteries to charge from a wall cube, since the ICs operate at the higher voltages that...
