AIC2364

AIC2364 4A Synchronous PWM/PSM Step-Down Converter with Light Load Efficiency  FEATURES  DESCRIPTION  2.5V to 6V Input Voltage Range The AIC2364 is a low-noise, pulse-width-  Adjustable Output Voltage from 0.8V to modulated (PWM), DC-DC step-down converter. Vin The device features an internal synchronous  4.0A Guaranteed Output Current rectifier for high efficiency; it requires no external  Up to 95% Efficiency on Heavy Load Schottky diode. The AIC2364 is ideally suited for (Vin=3.3V, Vout=2.5V, Iout=2.0A) Li-Ion battery applications. PWM/PSM mode  Up to 94% Efficiency on Moderate Load extends battery life and enhance efficiency by (Vin=3.3V, Vout=2.5V, Iout=200mA) switching to a pulse-skipping-modulated mode  Up to 93% Efficiency on Light Load during light loads. Shutdown mode places the (Vin=3.3V, Vout=2.5V, Iout=20mA)  Low RDS(ON) Internal Switches: 70mΩ  No Schottky Diode Required device in standby, reducing supply current to under 2µA. Other features of the AIC2364 include high  100% Duty Cycle in Low Dropout Operation efficiency for all load range, low dropout voltage,  Optional 550KHz/1.2MHz Operating Fre- short circuit protection, over temperature quency protection, and over voltage protection. It is  Optional Programmable Soft-Start (in DFN- available in SOP-8 and DFN-12 packages. 12) or Internal Fixed 1ms Soft-Start (in SOP- 8)  Optional Power Good Monitor (Only in DFN- 12 Package)  SCP, OTP, OVP  APPLICATIONS  L...
