- DESCRIPTION
- The AIC3402 is a high efficiency step-up DC/DC converter for applications using 1 to 2 NiMH bat-tery cells. Only three external components are re-quired to deliver a fixed output voltage of 2.0V, 2.2V, 2.7V, 2.8V, 3.0V, 3.3V, 5.0V. Fixed output voltage design can aid to reduce BOM cost and PCB area. The 3402 starts up from less than 0.75V(Typ.) input with 1mA resistive load which extends the battery operation time. Automatic PWM/PFM scheme brings optimized performance for applications with light output loading and low input voltages.
The space saving SOT23-3, SOT23-5, SC70-3 and SC70-5 packages make the AIC3402 an ideal choice of DC/DC converter for space con-scious applications, like wireless mouse, wire-less keyboard, electronic cameras, and wireless microphones.
