Analog Intergrations Corporation AIC2362
The AIC2362 is a low-noise, pulse-width- Adjustable Output Voltage from 0.8V to Vin modulated (PWM), DC-DC step-down converter. The AIC2362 is ideally suited for 96% Efficiency at Moderate Load Li-Ion battery applications. 100% Duty Cycle in Low Dropout Operation Other features of the AIC2362 include high Fixed 550k/1.1MHz Operating Frequency efficiency for all load range, low dropout voltage, Optional Soft-Start Internal Fixed 1ms Soft- short circuit protection, and over temperature Start protection.FEATURES
●DESCRIPTION
● 2.5V to 6V Input Voltage Range The AIC2362 is a low-noise, pulse-width-● Adjustable Output Voltage from 0.8V to Vin modulated (PWM), DC-DC step-down converter.
● 2.0A Guaranteed Output Current The device features an internal synchronous
● 93% Efficiency at Heavy Load rectifier for high efficiency; it requires no external (Vin=5V, Vout=3.3V, Iout=2.0A) Schottky diode. The AIC2362 is ideally suited for
● 96% Efficiency at Moderate Load Li-Ion battery applications. Automatic PWM/PSM (Vin=5V, Vout=3.3V, Iout=1.0A) mode extends battery life and enhance
● 90% Efficiency at Light Load efficiency by switching to a pulse-skipping- (Vin=5V, Vout=3.3V, Iout=20mA)
● Low RDS(ON) Internal Switches: 110mΩ modulated mode during light load. Shutdown mode places the device in standby, reducing
● No Schottky Diode Required supply current to under 2µA.
● 100% Duty Cycle in Low Dropout Operation Other features of the AIC2362 include high
● Fixed 550k/1.1MHz Operating Frequency eff...
