AN8018SA

Voltage Regulators AN8018SA 1.8-volt 2-channel step-up, step-down, or inverting DC-DC converter control IC Unit: mm s Overview The AN8018SA is a two-channel PWM DC-DC converter control IC that features low-voltage operation. This IC can obtain the step-up, step-down and inverting voltages with a small number of external components. The minimum operating voltage is as low as 1.8 V so that it can operate with two dry batteries. In addition, since it uses the 16-pin surface mounting type package with 0.65 mm pitch, it is suitable for miniaturized highly efficient potable power supply. 5.0±0.2 16 9 (1.0) 4.4±0.2 6.4±0.3 0.15 −0.05 +0.10 0° to 10° 0.5±0.2 s Features (0.225) 0.65 0.22 − 0.05 +0.10 0.1±0.1 1.2±0.2 1 8 Seating plane Wide operating supply voltage range (1.8 V to 14 V) Incorporating a high precision reference voltage circuit SSOP016-P-0225A (allowance: ± 2%) Control in a wide output frequency range is possible (20 kHz to 1 MHz). Built-in wideband error amplifier (single gain bandwidth 10 MHz typical) Built-in timer latch short-circuit protection circuit (charge current 1.1 µA typical) Incorporating the under-voltage lock-out circuit (U.V.L.O.) (circuit operation-starting voltage 1.67 V typical) Dead-time is variable. Flatness of switching current can be obtained by staggering the turn-on timing of each channel. Built-in unlatch function When DT1 pin is low level, or DT2 pin is high level, independent turn-off is possible. Incorporati...
