CONNECTION DIAGRAMS
A low power sleep mode can be invoked through the SS
pin. Quiescent supply current in sleep mode is typically
less than 50 A. Two UVLO options are available. The
UC3870-1 is designed for logic level MOSFETs and has
UVLO turn-on and turn-off thresholds of 4.5V and 4.4V
respectively. The UC3870-2 is designed for standard
power MOSFETs and has UVLO turn-on and turn-off
thresholds of 10V and 9V respectively. A precision 2.5V
reference can supply 20mA to external circuitry. An error
amplifier with soft start, high bandwidth current amplifier,
and a synchronizable oscillator are additional features.
Available packages include 18-pin plastic and ceramic
DIP (N, J), 18-pin SOIC (DW), and 20-pin plastic and
ceramic leadless chip carriers (Q, L).
