•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 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 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
