AN8018SA 1.8-volt 2-channel step-up, step-down, or inverting DC-DC converter control IC
Unit: mm
Overview The AN8018SA is a two-channel PWM DC-DC con- 5.0±0.2 verter control IC that features low-voltage operation.
This IC can obtain the step-up, step-down and invert- (1.0)
ing 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, 0° to 10°
since it uses the 16-pin surface mounting type package 0.5±0.2
with 0.65 mm pitch, it is suitable for miniaturized highly efficient potable power supply.
Features +0.10 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 k Hz 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. Incorporating a on/off control function (active-high control input, standby mode current: 5 µA maximum) Parallel operation is possible. Output block Totem pole 1 output Output source-current: −50 m A maximum (Constant current output with a less supply voltage fluctuation is possible by connecting an external resistor to pin 11) Output sink-current: +80 m A maximum Open-collector 1 output Output current: 50 m A maximum
Applications LCD displays, digital still cameras, and PDAs
