• Manufacturer Part Number: NCP1422
• Description: Sync-Rect PFM Step-Up DC-DC Converter
• Manufacturer: ON Semiconductor

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values
(not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage
may occur and reliability may be affected.
1. This device contains ESD protection and exceeds the following tests:
2. The maximum package power dissipation limit must not be exceeded.
3. Latchup Current Maximum Rating: ±150 mA per JEDEC standard: JESD78.
4. Moisture Sensitivity Level: MSL 1 per IPC/JEDEC standard: J−STD−020A.
5. Measured on approximately 1x1 inch sq. of 1 oz. Copper.

Output Voltage Feedback Input.
Low−Battery Detector Input and IC Enable. With this pin pulled down below 0.5 V, the device is disabled and
enters the shutdown mode.
Open−Drain Low−Battery Detector Output. Output is LOW when V
shutdown mode.
No Connect Pin
1.20 V Reference Voltage Output, bypass with 300 nF capacitor. If this pin is loaded, bypass with 1.0 mF
capacitor; this pin can be loaded up to 2.5 mA @ V
Battery input connection for internal ring−killer.
Ground.
N−Channel and P−Channel Power MOSFET drain connection.
No Connect Pin
Power Output. OUT also provides bootstrap power to the device.
