Description

SYNC/SD 13 RT 14 1.8 V(MIN) 1.24 V VREF PWM OSC VPUMP 7 VIN 9 CHARGE PUMP VPUMP 8 CP 3 VOUT 2 RSEN RECT 4 ANTI CROSS COND. ION VOUT 50 mV TYP The UCC39421 family of synchronous RESET PWM controllers is optimized to operate 1 from dual alkaline/NiCd cells

Features

include pulse-by-pulse current limiting, and a low 5-µA quiescent current during shutdown. The UCC39422 incorporates programmable power-on reset circuitry and an uncommitted comparator for low voltage detection. The available packages are 20-pin TSSOP or 20-pin N for the UCC39422, and 16-pin TSSOP or 16-pin N for the UCC39421. absolute maximum ratings over operating free-air temperature range (unless otherwise noted)Ĕ} Supply Voltage (VIN, VOUT,VPUMP).
