Description
19-0171; Rev 1; 9/93 High-Efficiency PWM, Step-Down P-Channel DC-DC Controller _______________General .
Features
* a 2V ±1.5% reference, a comparator for low-battery detection or level translating, as well as soft-start and shutdown capability. The MAX746, discussed in a separate data sheet, functions similarly to the MAX747, but it drives N-channel logic level FETs on the high side. ___________________________Applications
* High efficiency is maintained with light loads due to a proprietary dual-control (Idle-Mode™) scheme that minimizes switching losses by reducing the switching frequency at light loads. The low 800µA quiescent current and ultra-low 0.6µA shutdown current further extend battery life. External componeMAX747 Distributors
