Description

The NCP1450ASN50T1G is a PWM step-up DC-DC Switching Controller IC, specially designed for powering portable equipment from one or two cells battery packs. The NCP1450ASN50T1G series have a driver pin, EXT pin, for connecting to an external transistor. Large output currents can be obtained by connecting a low ON-resistance external power transistor to the EXT pin. The device will automatically skip switching cycles under light load condition to maintain high efficiency at light loads. With only six external components, this series allows a simple means to implement highly efficient converter for large output current applications.
86% at IO = 200mA VIN = 2.0V, VOUT = 3.0V, 88% at IO = 400mA VIN = 3.0V, VOUT = 5.0V High Efficiency
Low Startup Voltage of 0.9V Typical at IO = 1.0mA
Operation Down to 0.6V
1.9, 2.7, 3.0, 3.3 and 5.0V (with High) Standard Voltages
±2.5% Accuracy
Low Conversion Ripple
High Output Current up to 1000mA (3.0V Version at VIN = 2.0V, L = 10µH, COUT = 220µF)
Fixed Frequency Pulse Width Modulation (PWM) at 180kHz
Chip Enable Pin with On-chip 150nA Pullup Current Source
Maximum ratings are those values beyond which device damage can occur.
