NCP1410-NCP1410DMR2
250 mA Sync-Rect PFM Step-Up DC-DC Converter with Low-Battery Detector
NCP1410
250 mA Sync-Rect PFM
Step-Up DC-DC Converter
with Low-Battery Detector
NCP1410 is a monolithic micropower high frequency Boost
(step–up) voltage switching converter IC specially designed for
battery operated hand–held electronic products up to 250 mA loading.
It integrates Synchronous Rectifier for improving efficiency as well as
eliminating the external Schottky Diode. High switching frequency
(up to 600 kHz) allows low profile inductor and output capacitor being
used. Low–Battery Detector, Logic–Controlled Shutdown and
Cycle–by–Cycle Current Limit provide value–added features for
various battery–operated applications. With all these functions ON,
the device quiescent supply current is only 9.0 μA typical. This device
is available in space saving compact Micro8 package.
Features High Efficiency up to 92% Very Low Device Quiescent Supply Current of 9.0 �A Typical Allows use of Small Size Inductor and Capacitor Built–in Synchronous Rectifier (PFET) Eliminates One External
Schottky Diode High Switching Frequency (up to 600 kHz) Allows Use of Small
Size Inductor and Capacitor High Accuracy Reference Output, 1.19 V ± 0.6% @ 25°C, can
supply more than 2.5 mA when VOUT ≥ 3.3 V 1.0 V Startup at No Load Guaranteed Output Voltage from 1.5 V to 5.5 V Adjustable Output Current up to 250 mA @ Vin = 2.5 V, Vout = 3.3 V Logic–Controlled Shutdown Open Drain Low–Battery Detector Output 1.0 A Cycle–by–Cycle Current Limit Low Profile and Minimum External Parts Compact Micro8 Package
Typical Applications Personal Digital Assistant (PDA) Handheld Digital Audio Product Camcorders and Digital Still Camera Hand–held Instrument Conversion from One or Two NiMH or NiCd, or One Li–ion Cell to
3.3 V/5.0 V
