1 / 2 page 78 ICs ■Features • Surface-mount package (TSSOP24) • High efficiency due to synchronous rectifica- tion: 93% (at VIN = 5V, IO = 1A, VO = 2.5V) • Capable of downsize a choke-coil due to IC's high switching frequency (125kHz typ, On Time Control). (Compared with conventional Sanken devices) •Low reference voltage (Vref) of 1.1V. The output voltage is variable from 1.1V to 6V. • High-speed response to a load • Compatible with low ESR capacitors • Soft start and output ON/OFF available • Built-in overcurrent protection circuit • PWRGD function to indicate the output voltage status •High precision reference voltage: 1.1V ± 1.2% ■Absolute Maximum Ratings Unit V V V V V °C °C Ratings 7 25 30 VCC 7 +150 –40 to +150 Symbol VCC VIN VH VEN VPWRGD Tj Tstg Parameter Control-System DC Input Voltage DC Input Voltage Boost Block Input Voltage EN Terminal Input Voltage PWRGD Terminal Applied Voltage Junction Temperature Storage Temperature (Ta=25 °C) ■Recommended Operating Conditions Parameter Control System Input Voltage Range Input Voltage Range Output Voltage Range Operating Temperature Range Symbol VCC VIN VO Top Unit V V V °C Ratings 4.5 to 5.5 3 to 18 1.1 to 6 –20 to +85 ■Electrical Characteristics (Ta = 25 °C unless otherwise specified) Unit V mV/ °C mA mA µA µA V V µS µS V µA Ω Ω Ω Ω V µA µA V V µA V V V µA µA Symbol VO ∆VO/∆T Iop Iop Istd1 Istd2 Vuvlo1 Vuvlo2 Ton Toff Vref Iref RonHH RonHL RonLH RonLL VH-VLIN Ilim Iss Vcelo Vcehi ICE Vsens Vsens Vpwrgd Ipwrgd Ipwrgd Ratings min. typ. max. –1.2% 1.1 +1.2% ±0.03 6 1 100 50 3.7 4.4 2.5 2.9 2 1 1.1 1.2 1.3 100 5.5 5.5 5.5 5.5 4.5 5 5.5 90 100 110 ±20 0 0.8 2.4 VCC 5 1.32 0.88 0.4 120 5 Conditions VIN=5V, VCC=5V, VSNS connected to VO, IO=0A VIN=5V, VCC=5V, VSNS connected to VO, IO=0A, Ta=0 to 85 °C VCC=5V, EN=H, FADJ:open VIN=5V, EN=H VCC=5V, EN=L VIN=5V, EN=L VIN=5V VCC=5V VCC=5V, VIN=5V, VO=2.5V VCC=5V VCC=5V VCC=5V VH-VLIN=5V VH-VLIN=5V VCC=5V VCC=5V VCC=5V, VIN=5V VCC=5V VCC=5V VCC=5V VCC=5V, EN=5V VCC=5V VCC=5V VCC=5V, Ipwrgd=120 µA VCC=5V, Vpwrgd=0.4V Vpwrgd=5V Surface-Mount, Synchronous Rectifier Step-down Switching Mode Regulator Control ICs SI-8011NVS ■Applications •Power supplies for notebook PCs and mobile devices • Onboard local power supplies •OA equipment •For stabilization of the secondary-side output voltage of switching power supplies Dynamic Characteristics Circuit Current Undervoltage Lockout On Time Control High Side Drive Low Side Drive Bootstrap Protection System Parameter Output Voltage Temperature Coefficient of Output Voltage Circuit Current (VCC Terminal) Circuit Current (VIN Terminal) Standby Current 1 (VCC Terminal) Standby Current 2 (VIN Terminal) UVLO Operating Voltage 1 (VCC Terminal) UVLO Operating Voltage 2 (VIN Terminal) On Time Minimum Off Time REF Terminal Voltage REF Terminal Source Current On Resistance (high side) On Resistance (low side) On Resistance (high side) On Resistance (low side) Bootstrap Voltage Current for Current Limit Detection Soft Start Terminal Current EN Low Level Voltage EN High Level Voltage EN Bias Level Current PWRGD Good Voltage (high side) PWRGD Good Voltage (low side) PWRGD Low Output Voltage PWRGD Terminal Current PWRGD Leakage Current 1-1-2 Switching Mode Regulator ICs |
