AN8018SA
1.8-volt 2-channel step-up, step-down,
or inverting DC-DC converter control IC

Overview
The AN8018SA is a two-channel PWM DC-DC con-
verter control IC that features low-voltage operation.
This IC can obtain the step-up, step-down and invert-
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,
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.

Features
Wide operating supply voltage range (1.8 V to 14 V)
Incorporating a high precision reference voltage circuit
(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
μ
A 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
μ
A maximum)
Parallel operation is possible.
Output block
Totem pole 1 output
Output source-current:
50 mA maximum
(
Constant current output with a less supply voltage fluctuation is
possible by connecting an external resistor to pin 11)
Output sink-current:
+
80 mA maximum
Open-collector 1 output
Output current: 50 mA maximum

Applications
LCD displays, digital still cameras, and PDAs
