AX3702AB规格书详情
GENERAL DESCRIPTION
AX3702 is a high efficiency monolithic synchronous buck regulator using a constant on-time (COT) architecture. The device is available in an adjustable version. Supply current with no load is about 30uA and drops to <1uA in shutdown. The 2.5V to 6.0V input voltage range makes AX3702 ideally suited for single Li-Ion, two to four AA battery-powered applications. 100% duty cycle provides low dropout operation, extending battery life in portable systems. The constant on-time control scheme simplifies loop compensation and offers excellent load transient response. The high gain error amplifier in the control loop provides excellent load and line regulation. Proprietary adaptive on-time helps AX3702 to achieve nearly constant switching frequency across load range. AX3702 has cycle-by-cycle current limit and hiccup mode to protect over-load or short circuit fault conditions. Switching frequency is internally set at 1.5MHz, allowing the use of small surface mount inductors and capacitors. The internal synchronous switch increases efficiency and decreases need of an external Schottky diode. Low output voltages are easily supported with the 0.6V feedback reference voltage. AX3702 is available in small SOT-23-5L, SOT-23-6L, TDFN-10L (3*3), and SOP-8L-EP packages.
